Raleigh, NC's WRAL testing MPH mobile DTV system


Although Raleigh, North Carolina is set to become one of the first DVB-SH test markets in America, WRAL is already testing out yet another standard. The station known nationwide for taking its local newscasts to the world of HD while everyone else sat and moped in their SD control rooms is currently teaming with CBC in order to test out the ATSC-compatible MPH mobile television transmission system. As we've seen before, the system enables "local broadcasters to deliver digital television to mobile devices including cellphones, laptops and personal media players," all while moving quickly in vehicles, hoverboards, rocket-powered scooters -- you name it. There's no word on what exactly will happen once the trials conclude, but we'll be keeping an ear to the ground just in case it's something big

BlackBerry KickStart 8220 gets really early review


The Bold is still stealing the overwhelming majority of RIM's spotlight at the moment for a handful of pretty good reasons: one, it's actually been announced; two, it's 3G; and three, it falls in line with the traditional (and loved) BlackBerry form factor. Lurking in the shadows, though, is the KickStart, RIM's very first flip phone, and a device that could end up making a huge splash if it actually manages to launch at the sub-$50 price point that's been making the rounds on the rumor circuit. CrackBerry got a way-early peek at the 8220 version of the device, which follows RIM's typical naming convention by packing WiFi while an 8210 will hold up the GPS side of things (seriously, RIM, how hard can it be to do both?), and overall it seems that the R&D team did its homework from the quick impressions. The SureType keyboard is huge and apparently quite easy to use without making the phone excessively large, though the trackball rests deeper in the shell making it a bit trickier to operate -- you win some, you lose some. The QVGA display is said to be just shy of Bold quality (which is a compliment, considering the killer screen on the Bold), and it's always hard to argue with a 3.5mm headphone jack. Come on, T-Mobile, let's make this happen.

Windows iPhone 3G jailbreak tool released


Sure, it was already possible (if complicated) to jailbreak a first-gen iPhone running the 2.0 software under Windows, but this is the one-click tool all you crazy cats with those extra G's need if you don't have a Mac -- too bad no one's come up with a better name than "pwn" yet. Please, people. Let's do better

What cell phones work where?

Several readers have various questions related to cell phone networks and carriers. We take an in-depth look to come up with some answers.

AT&T Wireless

AT&T Wireless owns and operates a GSM 850/1900 MHz network. The safest way for AT&T customers to buy unlocked phones, is by choosing phones that are supporting both frequencies. AT&T's 3G network operates on the same frequencies. In addition, AT&T has licensed portions of the 1700 MHz frequency (AWS spectrum), which will likely be used to enhance its 3G capacity in certain areas.

T-Mobile

T-Mobile USA owns a GSM network operating on the 1900 MHz frequency. To further enhance its network coverage, the carrier is also seamlessly using AT&T Wireless' 850 MHz frequency when their own network is not within reach. Since most European handsets are supporting GSM 1900 MHz, T-Mobile USA's customers can pretty much choose from any European handsets available via online retailers like Amazon. Just make sure to check out T-Mobile's coverage map first, which distinguishes T-Mobile's 1900 MHz coverage from the 850 MHz roaming. T-Mobile does currently not offer 3G, but a network is currently being deployed on the 1700 MHz frequency (AWS spectrum).

Sprint

Sprint owns and operates a CDMA network operating on 800 and 1900 MHz frequencies. Only phones that are originally purchased with a Sprint subscription will work on this network. In order for a Sprint phone to for instance work on Verizon Wireless' network, the phone would need to be flashed with firmware from Verizon Wireless and tested on Verizon Wireless' network. Sprint uses the 2100 MHz frequency for its EV-DO data services, and is currently also deploying a Mobile WiMAX network on the 2500 MHz frequency.

Verizon Wireless

Verizon Wireless owns and operates a CDMA network operating on 800 and 1900 MHz frequencies. Only phones that are originally purchased with a Verizon Wireless subscription will work on this network. In order for a Verizon Wireless phone to for instance work on Sprint's network, the phone would need to be flashed with firmware from Sprint and tested on Sprint's network. Verizon Wireless uses the 2100 MHz frequency for its EV-DO data services, and will soon begin trials for its 4G network to operate on the 700 MHz frequency.

iPhone 3G vs. Windows Mobile smartphones

The Apple iPhone 3G can do everything, right? Not so fast. Infosync editor Philip Berne talks about his favorite features on Windows Mobile smartphones, features the Apple iPhone still can't match.

The Apple iPhone 3G is currently our multimedia smartphone of choice, but that doesn't mean it's the perfect phone. In fact, we think that Apple could learn a lot from its oldest nemesis, Microsoft. For all its flaws, there are some things that Windows Mobile does quite well, better than any of its competitors, in fact. The smartphone market is all about operating systems these days. Google's Android is on the way. Palm's newest OS is around a very long, sharp corner. RIM's BlackBerry OS will get an update on the BlackBerry Bold this year, and even Symbian has been forming new partnerships and gaining new ground. Here are a few things that the beast from Redmond can teach the rest of the pack, especially Apple's rarefied device.

1. Scheduling and productivity

Like many business folks, our job sometimes seems to revolve around meetings, so a good calendar app is a must for a smartphone. Microsoft's OS includes a feature for scheduling that is so simple, it's obvious. With Windows Mobile smartphones, you can invite other people to meetings. It works the same as on Outlook, which is no coincidence. We've never scheduled a meeting for just ourselves alone, so inviting our colleagues is a must. WinMo offers this feature and the best integration with our desktop Outlook client.

Windows Mobile also comes preloaded with Microsoft's Mobile Office suite. There are plenty of great options for opening office documents, some that might even be better than Microsoft's own edition. DataViz's DocumentsToGo and QuickOffice both come to mind. These are all good options, but Windows Mobile is the only one to offer real Office document editing on every single phone. From the lowliest clamshell to the high-end AT&T Tilt, everyone can read and edit Word, Excel and even simple PowerPoint documents.

2. Searching for contacts and other stuff

On a Windows Mobile smartphone, from the Today screen, when you start typing a name, the phone instantly pulls up your contacts and starts narrowing the list as you type. You don't have to go digging through menus to find your address book, or remember keyboard shortcuts. Other phones have started using this same trick, and we love it. It's the quickest, most convenient way to find a contact, and it's a great reminder that whatever else the device can do, at heart it's really a phone.

Microsoft's Windows Mobile has also pushed searching to the top level, up to the Today screen. On the last Windows Mobile smartphone we tested, the Palm Treo 800w, the Today screen was dominated by searching of all types. There was Internet searching via Windows Live, and also location-based search using the Treo's GPS and Palm's own point-of-interest database. Sure, any smartphone can perform the same functions, but we like that Microsoft has made searching a real priority on Windows Mobile, and so looking up contacts, looking up answers on the Web and searching for a local coffeeshop or gas station is quick and easy on a WinMo device.

3. Tethered modem support

When we're on the road, which is quite often, we hate relying on hotel Wi-Fi services that overcharge for limited use or, even worse, having to find a free Wi-Fi spot. We prefer to rely on our 3G smartphone to connect us to the Internet. While most smartphones, except for the Apple iPhone, can handle this task fairly easily, there is no easier way to connect your laptop to the rest of the world than Windows Mobile's Internet Sharing app. It isn't a program that every carrier and manufacturer uses, but when we find it on a smartphone, we feel like we've struck 3G gold. It's so simple to use: simply press the "Connect" button, plug your phone into your laptop and you're all set. No proprietary software, no confusing dial-up prompts. Just one touch and you're surfing the Web. This is how every smartphone should connect.

4. A variety of devices

One of the best things about Windows Mobile is that it scales nicely to a variety of devices. Unlike any other smartphone OS, WinMo shows up on full-QWERTY touchscreen phones, QWERTY slab phones with no touchscreen, and even simple clamshell phones with only a numeric keypad for input. There are Windows Mobile smartphones with no hardware keyboard at all. You might expect that only the Professional, touchscreen version of the OS is worthwhile, but in fact the Standard edition, which works on non-touch phones like the Motorola Q9 and Samsung BlackJack 2, might be even better, thanks to some recent improvements to the Today screen and the user interface. All Windows Mobile phones perform the feats we've discussed, from contact searching through real Office document editing. The ubiquity of the OS is impressive, and even venerable smartphone makers, like Nokia with their Symbian S60 OS, are trying to catch up to the breadth of device options Windows Mobile offers.

5. If you don't like it, change it

One of the nice things about Windows Mobile is that it doesn't have to look like Windows Mobile. Of course the user can hack into the phone's registry file and mess around there, but that's beyond our ability and interest. What we really mean is that manufacturers have been doing a very good job streamlining and in some cases hiding Windows Mobile from the user. HTC comes to mind first, of course, with their TouchFLO interface on the HTC Touch and the new HTC Touch Diamond. But even Sony Ericsson has gotten into the Windows Mobile game, and we doubt that users of the upcoming Sony Ericsson Xperia X1 smartphone will even notice that there's a Start menu under all that glitz and glamour.

For any other smartphone OS maker, such camouflage would be an anathema. But Microsoft has unashamedly embraced these modifications, and the Windows Mobile market is better because of it. Of course, we would prefer to see Windows Mobile with a shiny new user interface of its own, which would relieve the necessity for such modifications. But until a new version of the OS surfaces, we're content to enjoy these important smartphone features, and we're unwilling to toss our Windows Mobile phone aside completely in favor of the Apple iPhone.
