One welcome sign is an effort by companies trying to improve Microsoft Corp.’s (MSFT) Windows Mobile operating system, which has a reputation for confusing navigation and hasn’t had a major update recently. Kinoma Inc., for example, recently released an application called Kinoma Play that runs on Windows Mobile devices and gives users a markedly better way of handling photos, videos, music and Web browsing.

The HTC Touch Diamond, due out this month from Sprint, tries to hide Windows Mobile software.

This week, I tried yet another software program that is designed to run on top of Windows Mobile software. But this time, the software is at the heart of a device designed by the same company: HTC Inc. I tested the HTC Touch Diamond, due out from Sprint (S) sometime this month for $250 (after a $100 mail-in rebate) with a two-year contract.

Taiwan-based HTC started out in 1998 as a maker and designer of mobile devices for other companies. A year ago, HTC launched the first device under its own name in the U.S., and now, Sprint, AT&T (T) and T-Mobile (DT) sell HTC-branded devices. The Diamond incorporates HTC software, as well as software from Sprint, MobiTV, TeleNav and others. But it isn’t a stretch to imagine HTC trying to create a fully end-to-end model (hardware and all software) in the future.

The Diamond has a touch screen, but it’s smaller than Apple’s (AAPL) iPhone — 2.8 versus 3.5 inches. This screen lacks the iPhone’s multitouch functionality, and its smaller size robs space used for touch gestures like flicking or scrolling with a finger. Yet like the iPhone, it relies solely on an on-screen keyboard for all text entries. Even with the Diamond’s stylus, the keyboard felt small and cramped. Using just your fingertips was next to impossible.

After using the Diamond for a week, I can say that despite its handsome TouchFLO 3D software and animated icons like photos that flip from one to the next with a flick of finger, this device failed to disguise the frustrating interface of Windows Mobile often enough for my taste.

It reminded me of the brown paper bag book covers my Dad helped me make for schoolbooks when I was a kid: They looked great on the outside, felt sturdy and clean and created a blank canvas for homemade doodles that were often more interesting to me than the books they covered. But my book covers couldn’t change what was underneath; pages of frustrating algebra were just a flip away.

HTC’s sleek software tries to hide Windows Mobile, but menus from the Microsoft operating system are constantly popping up. HTC’s email program, for example, is represented by an animated envelope icon that, when selected, cleverly flips twice before sliding an email message half-way out and giving you a three-line peek at what’s inside. If only reading and responding to email were half as entertaining. Selecting the animated envelope opens the old, cumbersome Windows Mobile email program.

Also, the touch capabilities of the Diamond’s screen didn’t work as well as they should. Finger flicks that should have scrolled through lists instead seemed to select individual items in a list, as if they were sticky.

The Diamond isn’t all bad, of course. Plenty of people will like its smaller size because the iPhone and RIM’s (RIM) BlackBerrys seem too large and brick-like to hold up to an ear for phone calls. Next to my BlackBerry Curve, the Diamond was of comparable thickness but measured smaller in width and length.

Despite its size, the Diamond is packed with features. It has a 3.2-megapixel camera with autofocus that doubles as a camcorder, and comes with four gigabytes of internal memory and a removable battery. I taped short videos — something the iPhone can’t do — and found the sound and video footage to be adequate.

HTC touts the Diamond’s browser, which is based on the Opera browsing engine but is designed for HTC. It opens Web pages in views that fit the screen and text is automatically resized as users zoom in or out, though this resizing was sometimes slow.

Unlike the iPhone, Web sites that are opened on the Diamond’s browser don’t resemble the actual site as you would see it on your computer. I opened CNN.com (TWX) and WSJ.com (NWS), two sites that are packed with text and graphics on a regular browser. On the Diamond, they quickly were rendered in list format with mostly text-only. I easily touched the screen to follow links to full stories.

Like the iPhone, the Diamond has an accelerometer, though it’s called the “G-Sensor.” When it worked, this feature flipped the screen to match the horizontal or vertical direction in which the device was being held. Photos flipped instantly, but the Diamond’s G-Sensor took almost three full seconds to respond as I flipped from vertical to horizontal while using the browser. And some Web sites didn’t respond to the G-Sensor flips at all.

A special YouTube application developed by HTC was easy to find on the device and worked quickly. My videos were organized into categories for All, History, Bookmarks and Search, though this last category required using the finger-fumbling keyboard. In one step, I emailed a link from a YouTube video to a friend using the device, with a still shot from the video included in the message.

Overall navigation on the Diamond isn’t as intuitive as on the iPhone or iPod Touch, nor was it as easy as on a touch-screen Windows Mobile device running the Kinoma Play application. The iPhone and iPod Touch use quick double-taps on touch screens to zoom in or out, and multitouch capabilities resize images with pinching gestures; Kinoma Play uses a long touch to zoom in. The Diamond used double tapping on some screens, but not enough for me to grow comfortably reliant on it. A small, circular pad beneath the device’s touch screen provided a more dependable method for zooming in or out of screens: tracing the perimeter of this circle clockwise with a finger zoomed in; counterclockwise zoomed out.

The HTC’s software animation is put to good use on its Weather screen. Here, animated illustrations of each day’s weather appear on the screen: suns spin, clouds move in, rain appears to fall. Even moons appear on the device at night to accurately reflect the weather in a city at a specific time.

It is exciting to think about other mobile-phone companies giving better software a real try, especially those that attempt to improve Windows Mobile. But HTC’s Touch Diamond doesn’t hide the outdated operating system well enough or often enough for a user to want to buy a whole new mobile device.

Bet you’re thinking about Apple’s (AAPL) iPhone.

I’m actually describing a Windows Mobile device. In fact, any touch-screen Windows Mobile device made in the past couple of years can perform the aforementioned functions — as long as it’s running a new application called Kinoma Play.

This much-needed shot in the arm for Windows Mobile comes from Kinoma Inc. and for $30 can be downloaded onto a computer or directly onto a device from www.kinoma.com. It works on touch and nontouch screens alike, though touch features do add a lot of pizzazz. After installation, Kinoma Play seems to totally take over the device’s multimedia functions, hiding every trace of Windows Mobile’s clunky, antiquated, menu-driven operating system.

Kinoma Play in action, clockwise from top left: a media interface, touch-screen navigation, upload to YouTube, picture rotation, search by characters, and photo zoom.

It smoothly opens and displays all types of media, including photos, videos and music. But it’s also a fast search engine for multimedia content on the phone, on the Web or even on your computer via remote search. Kinoma Play works with services including YouTube, Audible, Flickr, iDisk, Live365, Orb and SHOUTcast. And a section called the Kinoma Guide compiles over 100,000 podcast episodes, radio stations, videos, live television and Webcam clips, panoramas and photos into easy-to-browse categories.

After almost a week with this application, I changed the way I thought about on-the-go Web browsing for media. I forgot about typical browser functions like typing a Web site’s name into a URL bar and instead did plenty of things online with my portable device without deliberately thinking about being online.

Kinoma Play is so well-designed that I wish it could entirely replace the dated Windows Mobile user interface, which still lags behind the iPhone’s. But, alas, it’s about media only. It isn’t designed to supplant, and doesn’t change or improve, any of the phone’s more common functions, like overall email and Web browsing, calendar, contacts or productivity programs.

Kinoma is working on Symbian, Linux and even iPhone versions of its application and will release one of those versions by the end of this year.

I ran into a few problems while using Kinoma Play. On three different occasions using two different devices, my touch screen froze when I tried to start the application, and the only way I could fix the problem was by completely rebooting my device. Once in a while, I experienced slow performance, though this could have been attributed to my network connection. And Kinoma Play lacks a one-step shortcut to its home screen; currently, users must press a “Back” soft key on each screen until they reach the home screen.

But the pluses of Kinoma Play outweighed these hassles, especially considering how enjoyable this application was to use. I tested Kinoma on two Palm (PALM) devices running Windows Mobile: the not-yet-released Treo Pro, which will be available here in the fall for an unlocked, unsubsidized price of $549, and the $250 (after discounts and two-year-contract rebates) Treo 800w available from Sprint (S). Both have touch screens that work best with an included stylus, though a fingernail or fingertip worked for me in most cases.

Upon installation, Kinoma Play automatically scans a device’s media and organizes it into categories under a section called My Media Files. I was especially eager to see how photos were handled, so I started out in the Pictures category.

All Kinoma screens have a set of familiar navigational tools that appear as soft keys at the bottom of the screen; they show up when the bottom section of the screen is touched and disappear when touched again. On the bottom left, a “Back” arrow takes users to the previous screen. On the bottom right, a list-like icon represents what Kinoma calls the Menu Pod. When touched, this pulls up three succinct menus — for media, settings and another action related to the program that’s open.

I opened some photos that were stored on the Palm Treo Pro and touched the center of the screen with my finger. A quick tap on the screen zooms in on each photo, and a small inset of the photo with a box representing the magnified area appears on the lower right of the screen. I dragged this tiny box around in the inset image to change where I was zooming. To zoom in on a photo slowly, I simply touched and held my finger on the screen for a longer period of time. A quick tap after either zooming method will quickly snap the image back to normal view.

I moved from one photo to the next as I do on my iPod Touch: by placing a finger on one edge of the photo and flicking left or right across the screen. Rotating was fun and easy to do when I drew a circle on the photo with my fingertip in the direction that I wanted it to rotate. The image followed whatever motion I drew. To rotate the photo 180 degrees, I drew a larger half-circle.

I selected Flickr from Kinoma Play’s list of services and signed into my Flickr account in just a few steps. My photos and those of friends were just as easy to browse as my own photos, thanks to Kinoma Play’s built-in tools. The Menu Pod icon offered a one-step way to play all photos in slide shows; music could be selected to play in the background.

With a touch on the Menu Pod icon, users can add any media to favorites or to an “on-the-go” list. This same tool also sends multimedia to others via email; I used it to send friends photos of a recent trip to California as well as a YouTube link to video footage of Sen. Joe Biden speaking.

Kinoma makes something out of every action. The Menu Pod button seems to jump into the center of the screen when summoned, and each of its three menus spins like a tiny top to get out of the way so another menu can be seen. Other screens seemed to do a mini back flip as they opened or closed. And long lists seemed to bounce when scrolling reached the top or bottom.

In the Services menu, I used Audible to listen to part of an audio book and listened to rock and country songs on Web radio stations from SHOUTcast and Live365.

I particularly liked using the Kinoma Guide, which is constantly updated with material that streams to your devices when you open it. I found a Restaurant Guys podcast in which chef Cat Cora was interviewed, and even saved it for later listening by downloading this seven-megabyte podcast to my device in one clean step. Kinoma wisely adds all downloads to a special section that’s easy to find. The last 100 things you looked at on Kinoma Play can be found in a section called History.

These days in the tech world, much attention is being paid to applications sold on Apple’s App Store for use with the iPhone or iPod Touch. But Kinoma Play is one application that is desperately needed by Windows Mobile users, and it just might remind them that they can better navigate media-related Web services — without having to buy a new mobile device.

VTech Communications wants to put an end to this mad phone dash with its new $150 Expandable Cordless Phone System with Bluetooth, the LS5145. This device synchronizes with your cellphone and redirects incoming cell calls to ring wherever the VTech phones are placed in the house. It works with your landline and up to two Bluetooth-linked cellphones, and can be expanded using additional handsets that cost $80 each.

The $150 Expandable Cordless Phone System with Bluetooth from VTech Communications Inc.

The concept of a cellphone extender isn’t new, but not many of them have caught on. Another popular add-on to cellphones at home is the repeater, which focuses on boosting a phone’s signal in a place with poor coverage. The VTech 5145 could work as a repeater, assuming you put it and the finicky cellphone in a place with good coverage. But if your entire house has lousy cell coverage, it won’t work as a repeater.

AT&T licenses its corded and cordless phones through VTech, which sells a less-expensive product similar to the 5145 called the AT&T EP5632. It costs $100 and has the same basic functions as the 5145, but is clunky and much less stylish. Its additional handhelds cost $60 each.

This week, I put my feet up and tried the VTech 5145 and one of its accessory handsets, the LS5105. These phones are stylishly thin and have bright color display screens, which can be set to one of 27 still color wallpaper images or four animated designs. It took me only a minute to pair cellphones with the system using Bluetooth, a wireless technology that connects devices that are within about 30 feet of one another. And the VTech’s primary function — extending the cellphone throughout a house to make it more convenient to answer — worked well, ringing much louder than my cellphone.

But the 5145 didn’t display the numerous names and numbers stored on my cellphone’s contact list. Unless I wanted to painstakingly enter the data into the VTech, incoming calls were only identified with phone numbers, so I rarely knew who was calling. And I could only call the handful of numbers that I know by heart.

Bluetooth technology isn’t incapable of transmitting data: My BlackBerry Curve even tried to transfer its contacts to the 5145, but couldn’t. VTech chose to use headset Bluetooth synchronization on the 5145 rather than hands-free synchronization. Hands-free is the same technology used in most Bluetooth-equipped cars; it provides more access to the Bluetooth device, such as phone-book integration.

I also missed other features on my cellphone when it wasn’t by my side, such as text messaging and voice mail. Incoming text messages were sent to my cellphone unbeknownst to me since I wasn’t near it, and when I didn’t answer incoming calls through the VTech, I had no way of knowing if the caller left a voice mail on my cellphone.

The 5145 includes a base station and primary phone; the 5105 additional handset includes a small stand just big enough to hold it upright. I set up the base station near where I drop my work bag after coming home each night. After the initial pairing during setup, phones automatically link to the VTech, meaning I never had to take my cellphone out of my bag.

I paired the 5145 with two phones at once: a Motorola Razr using Verizon and a BlackBerry Curve with AT&T service. I also tested pairing a third phone with the system, the HTC Pocket PC 6800 from Sprint, though only two cellphones can be paired simultaneously. Just one of the Bluetooth phones can be used at a time, in addition to the landline. As long as the two paired phones stayed within about 30 feet of the base station, they automatically started routing calls through the VTech.

Call waiting worked like using my actual cellphone, except I pressed different buttons on the 5145 to “swap” calls. If you’re chatting on a landline call, you can answer an incoming cellphone call by placing the landline call on hold. If each line — landline and cellular — has call waiting, a total of four callers could potentially be linked to the VTech system at once.

In my house, we gave up our landline years ago, so I tested the system using only cellphones. I saved myself a few trips racing up and down the stairs to find where I had left my cellphone, instead placing the base station on one floor and the additional handset on the other. Using cordless phones for the first time in years reminded me of the issues that accompany this system. The line became fuzzy when I moved too far away from a phone’s base station, though VTech says a connection can stay clear for up to about 900 feet.

I almost forgot that cordless phones can’t be taken out of the house. While on a phone call, I had to stop myself from heading out the front door and continuing my chat as I walked to the corner store. Cellular calls that are in progress on VTech handsets can be continued on the cell by adjusting a setting on the cellphone, or by walking far enough away from the base station to receive a cellphone prompt to disconnect from the system.

I made calls from the handsets by first choosing which of the paired cellphones to use. My calls were received by friends and family just as if I was calling on my cellphone, though a couple of people told me that the connection didn’t sound quite as good.

Each handset is equipped with a speakerphone, and missed calls are noted on the color screen and in a call log, along with the date and time. A built-in intercom system lets handsets communicate with the other or the base station. Users can choose from one of 23 ringtone-like melodies; I chose a steel drum tune for one handset.

If you’re looking for an easier way to answer your cellphone whenever and wherever it rings, VTech’s system might be a good solution for you. But if you rely on your cellphone’s address book to identify callers and aren’t up for inputting these data again, it might be worth waiting for a Bluetooth cordless phone system that will automatically copy data from your cellphone.

MobiTV, from MobiTV Inc., www.mobitv.com, gives people a way to watch television on their cellphones.

For lovers of portable video, the arguments in favor of TV on phones are speed and convenience. Rather than waiting to download movies, video podcasts and TV shows to a computer and then to transfer them to a portable player like an iPod, some would rather see current, live content streamed onto the device they already carry — their cellphone — whenever they want, wherever they are.

Live TV on cellphones isn’t new. We first tested it in 2004. But it was awful then, choppy and almost unviewable, because the cellular networks were too slow and the phones were too wimpy. So I decided to try it again.

Many cellphones are capable of displaying streamed television using built-in services, but few people are aware of these capabilities and not every phone will work as well as the next. The best results are delivered on devices with good quality screens that can retrieve and display the content using high-speed networks.

I used a mobile content-streaming service called MobiTV on three phones serviced by two carriers, Sprint Nextel Corp. and AT&T Inc.’s Cingular Wireless, watching a variety of shows on screens smaller than the palm of my hand. Monthly usage for watching cellphone TV with these two carriers costs about $25 and $30, respectively, on top of your voice plan. MobiTV is compatible with more than 150 handsets, offering roughly 40 channels — about half of which show live content like that found on your home TV.

All in all, MobiTV offers a fun and simple solution for people seeking TV on the run. High-quality images appeared on screen just moments after I opened the MobiTV application and an on-screen guide labeled each channel. TLC, ESPN, The Discovery Channel, The Oxygen Network and major news channels are entertaining enough. And though my eyes hurt after 30 minutes of watching such a small screen, I only ran into a few other snafus: on-screen images disappearing while audio continued, certain channels cutting out and lips moving out of sync with audio. In more cases than not, these instances were rare or corrected themselves in seconds.

Other carriers offer video clips that might easily be confused with MobiTV Inc.’s technology. Verizon Wireless, for example, offers its V Cast service. But V Cast requires that you download clips onto your device. Sprint and Cingular also offer video-on-demand options. But the MobiTV service streams content onto your phone, showing it just about a minute later than the same content on live TV.

If you don’t use Sprint or Cingular and you’d like to download MobiTV to your standard cellphone, or to your Palm or Windows Mobile smart phone, you can do so through third-party vendors like Handango.com; these options can be found on www.mobitv.com. Vendors charge about $10 a month on top of any data charges that you might owe your carrier.

MobiTV’s service includes a channel guide.

Sprint and Cingular encourage you to buy an unlimited monthly data plan in addition to your voice plan if you’ll be watching TV on your cellphone. Sprint calls its live-TV service Sprint TV Live — though it’s really MobiTV beneath the covers — and offers TV-inclusive data plans for $15, $20 or $25. These return 8, 13 and 25 channels respectively. Sprint’s exclusive content includes the NFL network. To further confuse matters, you can also buy stand-alone Sprint TV Live on top of those three data plans; it costs about $10 monthly. Cingular charges users about $20 for its unlimited data plan plus $10 for MobiTV usage. This carrier keeps the MobiTV name.

MobiTV worked relatively the same way on all three handsets with both carriers: two Windows Mobile devices, the Sprint PPC-6700 and Cingular 8525, and a basic cellphone, Samsung Electronics Co.’s SGH-A707 with Cingular’s 3G network. In my tests, MobiTV came pre-loaded on the devices, letting me simply select it from a list to start watching streaming content.

On the Cingular 8525, a smart phone running the Windows Mobile 5.0 operating system, I browsed through a guide until I found The Oxygen Network. The Isaac Mizrahi Show, not a favorite of mine, was just ending. It was followed by a quirky game show called “Can You Tell?”

MobiTV streams two types of programs: Live and Made for Mobile. Live shows are like those on your regular TV though slightly delayed and with different commercials in the local ad slots. I watched MSNBC’s “Hardball With Chris Matthews” using MobiTV and my regular TV, and an interview with Mia Farrow started about a minute earlier on my TV than it did on my mobile device.

Made for Mobile channels include special MobiTV content, such as music-video channels, or content for certain channels that MobiTV stitches together to show in a better format for mobile. The latter is the case with ESPN; in 15 minutes, I watched clips about football, Nascar, baseball, boxing and basketball with only a few quick commercials. In these snippets, however, lips weren’t synched with the audio.

I often opted to view content in full-screen mode, which, in 10 seconds, alters the image to take over the whole screen in horizontal view. A few times, while watching full-screen view, my on-screen content froze and had to restart in the regular view.

MobiTV says that using its service to watch programs saps battery at a rate equal to that of voice calls.

People who use digital video recorders at home to pause or rewind live TV will be disappointed to find you can’t do that with MobiTV. The company is hoping to offer these capabilities in the future. But because of the smaller screen, you probably won’t want to watch your mobile screen for as long as you would a regular TV, reducing the need to pause and rewind.

MobiTV’s services will never replace your home-entertainment center experience. But the ability to watch TV on your phone is a great way to stay plugged into news and entertainment. Just be sure that you’re using a fast network and a generously sized screen.

Google has been branching out from its search-engine roots to offer a variety of Web-based applications. Some of these, especially Gmail and Google Maps, have been well received and are quite popular on computers. Now the company wants us to use these and other applications away from the computer, too — on mobile devices.

This week, we put Google’s suite of mobile programs through the ringer to see if we might let it infiltrate our on-the-go lifestyle as easily as we’ve let Google search become an everyday part of our computer’s browser. Google offers five Web applications for downloading onto your mobile device including Maps, Gmail, SMS, Search and News.

We focused on the first three programs to see how they would fare on a tiny device with a smaller screen that demands more scrolling to view information that is normally contained in a single screen on a computer.

Overall, we were pleasantly surprised by Google Maps for mobile, Gmail for mobile, and Google SMS (Short Messaging Service), a system that uses text messaging to find answers about certain topics. The programs are visually attractive on smaller screens, and didn’t require much practice, catering to people who want quick assistance without much fuss.

And Gmail for mobile lets you open attachments containing photos, Microsoft Word documents and PDFs — a capability typically only found on Treos, BlackBerrys and Windows Mobile smart phones, not cellphones.

Google Inc. isn’t alone in this field. Many companies, including its rival, Yahoo Inc., make mobile applications for cellphones, and this category is likely to keep growing.

We used three mobile devices for our Google tests: the $80 Samsung A900M cellphone from Sprint, the $225 Samsung Drift cellphone, from a new phone carrier called Helio and the $400 Palm Treo 700p with Verizon service (all prices include two-year contracts). Your cellphone carrier must use Java programming language to work with Maps and Gmail for mobile; Verizon does not. The Treo works with Google Maps for mobile but not with this new Gmail version. Any phone with text messaging capability can use Google SMS.

These Google mobile applications are free to download, but your cellphone carrier may charge you for Web browsing or text messaging, depending on your plan.

To download any of these applications, you can go to www.google.com/mobile and enter your cellphone number, triggering the site to send a text message to your device with a URL link for the program you want to download. Or you can enter the URL (found on the Web site) into your cellphone’s browser. We tried both methods with success, downloading Google Maps for mobile in 10 seconds during one test.

Our Sprint Samsung A900M came preloaded with Gmail for mobile, so we quickly entered our Gmail username and password to get started. In seconds, our screen was filled with up to six emails at a time, each clearly divided by lines. Each email’s subject, sender and date were visible on our tiny screen, written in a legible font that didn’t seem squeezed. New emails were listed in bold type.

We used the phone’s directional buttons to scroll up or down, highlighting and selecting emails to read them. Each email read much like on a computer screen, but (thankfully) without the advertisements that Gmail usually lists along the right side of a computer screen.

Email attachments were easy to open and read; we opened a Microsoft Word document and a digital photo in JPG format, the photo was shrunk to fit onto our phone’s screen so we didn’t have to scroll. Attachments can’t be edited.

You can perform every action in Gmail for mobile that you can in regular Gmail, including replying to and starring emails, searching through messages, reporting spam and archiving. We searched through emails for the word “Walt” and quickly got a list of relevant emails, and an email that we sent from the phone was received on the other end in seconds. Tasks performed in Gmail for mobile automatically synched with our Gmail account.

Google Maps for mobile was familiar and simple. After downloading it and opening it on our cellphone, we entered our ZIP Code and a map of Washington, D.C., appeared on the entire screen. A list with Find Business, Find Location and Directions options helped us narrow our search.

The select button on each of our devices zoomed in on the map, and scrolling around with directional buttons moved the map accordingly. We quickly switched between map view and satellite view, the latter showing us detailed aerial shots of our tree-filled neighborhoods. A Show Traffic option color-codes highways in 30 major cities to show how fast the cars in that area are moving.

We searched for our local Four Seasons hotel by typing “Four Seasons” into the Find Business section of Google Maps for mobile. Nine results were returned, the second was the hotel. The hotel’s address, phone number, parking fees, room rates and acceptable credit cards were also listed.

The Helio Samsung Drift cellphone comes preloaded with Google’s Maps for mobile, and also has built-in GPS capability. This feature lets you press “0″ when using Google’s mapping program on your phone; a tiny circle marks where you are on the map.

The Google SMS mobile tool is fun to use, and doesn’t require a download. We just sent questions via text message to GOOGL, or 46645 on the numeric keypad. Various data can be retrieved including local listings, weather, sports scores, trivia, movie times and translations.

We asked for George Bush’s age and got the 41st president’s birthday sent back in a text message a second after our question was sent (June 12, 1924, if you’re curious). While on the way to an Irish pub for dinner, we typed in the slightly odd name of the place and its ZIP Code (RiRa 22201) and got a local listing response, including the address and phone number for the two RiRa Irish Pubs in the area.

Sometimes we had to rephrase our inquiry to receive a helpful Google response, and if you don’t have text messaging included in your phone’s plan, this could get costly. But as we used Google SMS more, we got better at asking questions the right way.

If you use a computer every day, chances are good that you’re spoiled by being able to retrieve helpful data within seconds, thanks to the Internet. Google’s mobile applications give you that convenience on the go, in a way that doesn’t leave you missing your computer.

Everybody wants to be your cellphone company. It’s not just the traditional carriers, like Cingular or Verizon Wireless, that aim to provide wireless phone service. New brands, like ESPN and Helio, are entering the cellphone market. These new entrants don’t have to invest billions in building nationwide networks. They simply rent large chunks of capacity on existing networks, mainly Sprint’s, and then resell voice minutes and other features to consumers under their own brands, complete with their own phones, their own billing and their own customer service. They are called Mobile Virtual Network Operators, or MVNOs.

Disney Mobile offers a $59.99 Pantech cellphone (far left) and a $109.99 LG Electronics cellphone (middle) for use with its Family Center programs, which help parents keep tabs on their children’s cellphone usage. The Family Locator feature (above) uses GPS to locate children.

The latest MVNO is Walt Disney Co., which believes it can leverage its famous brand, and carve out a niche, with a “family friendly” cellphone company called Disney Mobile. The idea is to sell phones and services that make it easy for families to stay in touch while giving parents easy control over their kids’ cellphone activities.

These Disney cellphones allow parents to limit how many minutes their kids can use, with whom they are talking and when they use their cellphones. A parent can even learn where his or her child is using a GPS locator. Yet they do meet another need: giving kids a way to stay in touch with a phone that looks normal, even a little cool.

We’ve been testing Disney Mobile and, overall, we think it’s a smart idea. The phones were easy to operate without reading any directions, and restrictions can be set using the parent’s phone itself or the www.disneymobile.com Web site. We think it’s a good thing for parents to be able to set limits on kids’ cellphone privileges, and these phones offer a no-nonsense way of doing so.

But there are three big downsides to keep in mind. First, Disney Mobile is a cellphone company, not just a phone or a feature, so you have to switch your family from its current carrier and phones, or at least add one or more new contract and phone. Second, the company is new and small and offers just two phone models, not the dozens its rivals sell. Third, it runs on the Sprint network, so, if your Sprint coverage is poor, Disney Mobile won’t be a good choice.

This isn’t the first effort to make a restricted cellphone for kids. Over a year ago, we tested Firefly Mobile Inc.’s kid cellphones — tiny, glowing gadgets with only five buttons that were ideal for young kids who aren’t ready for cellphones with numeric keypads. The Disney Mobile phones are aimed at the next age group of “tweens” on up to teenagers, who would rather die than be caught using the odd-looking Firefly unit.

These phones are offered in two brands and prices: the $60 Pantech DM-P100 cellphone with a digital camera and the $110 LG Electronics DM-L200 phone with a digital camera and camcorder. (These prices require a two-year contract.) Both are flip phones with color screens and full numeric keypads, and they look and operate like regular cellphones. Disney-related themes like those from the movies “Cars” and “Pirates of the Caribbean” illustrate the navigational menus in each phone.

Voice and data plans can be purchased for individuals or families; family plans include two lines and additional lines can be added for $10 each. Plans range in monthly price from $40 to $250, but all include five free GPS “locates” per month. Neither phone can use Sprint’s latest, high-speed network for Web surfing and email. They are based on older technology.

Using the phones was easy. When you buy them — either from the Disney Mobile Web site, by calling 1-866-DISNEY2 or at kiosks in malls around the country — the phone’s owner is designated. A phone can be configured either as a parent’s phone or a child’s phone, even though they are physically identical. The parent’s cellphone has privileges and features that the child’s cellphone lacks.

A special Family Center menu within the phone offers four parental features: Family Locator, Family Monitor, Family Alert and Call Control. Another option within this menu called Shop Family will eventually offer various applications that compliment the Family Center programs; as of now these aren’t yet available.

We selected Family Locator on our parent phone (child phones can’t access this section), chose the name of the child whose phone we wanted to find and were asked for our four-digit PIN. In one test, after waiting for about 20 seconds while the screen read “Locating,” we received a message and map accurately finding our child-designated phone. It said the child’s phone was “Near [1707-1773] K St. NW, Washington, DC,” and said that was within 40 yards of the actual location.

But during other tests, Disney experienced problems with Sprint changing its network configuration, and we weren’t able to receive GPS information about our “child’s” cellphone. Disney fixed this after almost a whole day, but we wondered about parents who might have used the Family Locator during this outage, panicked to find their kids.

The Family Monitor section lets parents set allowances or view usage for each child’s voice, text, pictures and downloads. Parents can set allowances, see how much allowance a child has left in each section, and how much has already been used up. We noticed that the data for each updated whenever we closed and reopened the Family Monitor section.

The Family Alert section is filled with canned text messages that a parent or kid — each phone is set up accordingly — might send to one another. The parent’s quick alerts include “Can U get a ride?” and “Call me when U can,” while the child’s include “Can I hang out?” and the ever popular “What time is dinner?”

We easily sent these messages from one phone to the other by selecting them and hitting Send. The receiving phone got the incoming message, labeled as a “Family Alert!” so as to distinguish it from other messages. Unlimited intrafamily messaging is included in each plan.

All three of these sections can also be accessed on a computer at the www.disneymobile.com Web site, where you can see more details about each after entering log-in credentials and a PIN.

Call Control, the fourth section within Family Center, must be set up on the Web site. After you choose a phone, you can go through a simple chart to designate when your child can use his or her phone according to times and days of the week. Below this chart, a section lets you enter Always On numbers that the child can always call regardless of Call Control restrictions, such as 911 and numbers of relatives. Likewise, a section of Prohibited Numbers blocks all communication with certain numbers, including receiving or making calls and text messaging.

We restricted the child’s phone during certain times of the day, and when we tried to make a call from that cellphone during those times, it didn’t go through.

Disney Mobile is good news for parents who have had a hard time cracking the whip on cellphone usage and bad news for kids who sneak calls at all hours of the night or who run up their phone bills with text messaging. If you’re looking for a way to keep better tabs on your family’s cellphone usage, this system works well.

The cellphone — or, more accurately, the device formerly known as the cellphone — is getting to be more and more like a little portable computer. High-end models, known as smartphones, can handle large volumes of email, complete with attachments; surf the Web at high speed; view and edit Microsoft Office documents; take decent pictures; and play back music and videos.

To manage these laptop-like tasks, they come equipped with faster and faster processors; more and more internal memory; expansion slots for increasingly spacious memory cards; and small, but usable, keyboards, instead of mere phone keypads.

We’ve been testing two new such phones. One, from Palm Inc., is an improved model of the Treo, which has long been our favorite smartphone. The other, an entirely new design from Motorola Inc., manages to pack most of the Treo’s functionality into a much thinner and lighter body, at half the Treo’s price.

The new Palm model, called the Treo 700p, uses the Palm operating system and is being sold by both Verizon Wireless and Sprint Nextel Corp. for $399, with a service contract. The Motorola challenger, called the Q, uses Microsoft’s Windows Mobile operating system and is being sold by Verizon for $199, with a service contract.

The Q is the bigger news here. In the tradition of Motorola’s RAZR phone, the Q is a sleek, handsome devil. It demolishes the two biggest problems with smartphones like the Treo: They are bulky and expensive. The Q is a little wider than the Treo 700p, but it’s just half as thick and, at 4.06 ounces, is more than one-third lighter.

Unfortunately, its Microsoft software is much clumsier than the Treo’s Palm software, degrading its utility. Also, the Q’s screen is lower-resolution than the Treo’s and slightly smaller, and its battery life as a phone is weaker than the Treo’s. While the Q keyboard is larger than the Treo’s, we actually found it worse for typing.

Still, the Q is a decent solution for light email users and for those who have avoided a smartphone due to bulk and cost. We assume that, at $199, the Q will sell well and will challenge the Treo and BlackBerry in the marketplace.

However, we still prefer the Treo for serious users of mobile email, Web and Office. And the new model, with greater speed and other enhancements, only adds to the Treo’s strengths.

Both of these phones run on the new, broadband-like EV-DO data networks offered by Verizon and Sprint, so they are actually practical for Web browsing and for downloading big email attachments. In our tests, both registered speeds of between 200 and 500 kilobits per second, compared with about 70 kbps for the older Sprint and Verizon networks. Neither phone has Wi-Fi wireless capability.

The new Treo 700p is essentially the same as the Treo 700w introduced a few months back, except that the “p” model uses the Palm operating system, while the “w” model uses Windows software. Like the 700w, the newest model has a squarer shape than that of the older Treo 650. It also has bigger, better keys than the 650, roughly twice the usable internal memory and a higher-resolution 1.3-megapixel camera.

Also, the 700p now has — built into its memory — the excellent Documents To Go program from DataViz, which allows you to view, and in some cases edit, Microsoft Word, Excel and PowerPoint documents and Adobe PDF documents.

The main advantage of the 700p, however, is its ability to use the high-speed EV-DO network. And the new Treo can be used as a modem for a laptop, either via a USB cable or a wireless Bluetooth connection.

In our tests, over a couple of weeks, the Treo 700p performed well. Web browsing was a pleasure at the new high speeds. Our only complaint was a short but annoying lag in displaying the text of emails and in performing certain other operations. Also, our test unit crashed twice and had to be restarted. (It didn’t lose any data in the crash.)

The Q is a mixed bag. Its hardware is elegant. Its software is annoying, often requiring two clicks to do what takes one on the Palm.

Motorola chose a more stripped-down version of Windows Mobile software than the one used on previous keyboard phones, and it does work better one-handed. But it still requires many of the extra steps of its Windows sibling and yet lacks the touch screen and built-in Office programs of other Windows-based smartphones.

In our tests, we found the Q easy to carry, but often irritating to use. Things like muting the phone, locking the keyboard and even playing the built-in solitaire game took much more effort than performing the same tasks on the Treo.

The Q has four navigation buttons positioned below the screen like the Treo; like a BlackBerry, it has a scroll wheel and back button on the right edge. The Q’s keyboard has more space between each key than most smartphones, but the rounded shape of the keys themselves makes them uncomfortable to use for more than a few sentences of email.

The familiar green Send and red End keys are prominently located just above the keyboard, and number keys are distinguished in black. We chatted away using the Q’s phone, and it worked well on voice calls.

Special designated Back and Home keys are next to the Send and End keys, and two other buttons enable direct access to email and the Q’s digital camera.

We set up email accounts on the Q using EarthLink and Hotmail.com, but Windows Mobile software really started to get annoying while we were navigating through our email. Performing a task as simple as deleting a message requires two steps — selecting Menu, then selecting Delete — and we couldn’t find any way to highlight and delete a group of emails.

By contrast, on the Treo, using the major email programs, you can delete an email with one click and even clean out a whole inbox with a couple of clicks. This may not matter much to people who get little email, but for heavy users, it’s crucial.

We also had trouble with attachments on the Q. While we successfully received some pictures and documents, a test series of four emails, each with a different type of document attached, failed on the Q. On both of our test Q units, using two different email services, the four attachments simply disappeared, even though they came through fine on the Treo and on Windows and Macintosh computers.

Viewing Microsoft Office and PDF files on the Q is a more cumbersome process than on the Treo, and the files can’t be edited on the Q.

The 320×240 resolution on the Q’s screen is 25% lower than that of the Treo 700p, which has a 320×320-resolution screen. Many things — Web sites, photos, attachments — just didn’t look as good on the Q compared side-by-side with the Treo. The Q’s built-in 1.3-megapixel digital camera captured videos and still shots without a problem, but the view on our screen was cluttered by information bars at the top and bottom.

You might like the $199 Motorola Q because of its price tag or striking design. If you don’t use email too much, or if you’ve never used another smartphone, you might not miss the more user-friendly features that the Treo 700p has to offer. We wish that the sleekness of the Motorola Q could be combined with the intuitive features of the Treo 700p. For now, we’ll stick with what works best — the newest Treo.
