The AT&T Tilt features a slide-out full QWERTY keyboard and a tilting screen. The Windows Mobile 6 smartphone also offers the full gamut of wireless options, including 3G and GPS, push e-mail, a 3-megapixel camera, and support for AT&TMusic and Video.

Design
Let's just cut to the chase and talk about what makes the AT&T Tilt so special, shall we? From the outside, the Tilt doesn't look that much different from its predecessor, the AT&T 8525. It has a PDA-like design and features a slide-out screen that reveals a full QWERTY keyboard underneath. However, there's one major difference between the two: The Tilt's screen tilts (hence the name; get it?) up to 40 degrees, mimicking a mini laptop. Though we never had any problems with the old design, we do like this extra functionality. It gives you a better view of the display, and it's nice if you just want to lay it on a flat surface and read through your e-mails, work documents, or view videos. Of course, if you so choose, you could compose messages in this position, but you'd probably have to peck away with your index fingers, which seems a bit uncomfortable and dorky. We found it easier just to hold the smartphone in both hands and let our thumbs happily tap away.

The keyboard itself is roomy with large rectangular buttons that are tactile and well-backlit, so we were easily able to type out e-mails, text messages, and the like. The number buttons are also easy see, as they're highlighted in silver--a stark contrast to the rest of the black keys. The only real problem we ran into was trying to press the two soft keys above the keyboard while the screen was tilted up. Having the screen in the upright position reduces what little space there is between the soft keys and the bottom edge of the front cover, so we kept banging our thumbs up against it. It's certainly not a deal breaker, though, and we were happy with the overall experience.

The AT&T Tilt's touch screen measures 2.8 inches diagonally and shows off 65,536 colors at a 320x240 pixel resolution. Text and images looked sharp and bright, and the display was readable in various lighting conditions, including bright sunlight thanks to the tilting screen. You can change the theme of the Today screen as well as the background image, displayed menu items, and backlight timeout. The screen orientation will also automatically switch from portrait to landscape mode once you slide open the cover, but we noticed there was a slight delay during the transition (See Performance for more).

Below the display, you'll find a navigation array that consists of the Talk and End buttons, two soft keys, an OK button, shortcuts to Internet Explorer Mobile, the Start menu, and your Inbox, and a five-way navigation toggle with a central select key. All of these controls are easy to use, and we're particularly pleased with the spacious directional keypad. On the left spine, there is a push-to-talk launcher, an OK button, and scroll wheel that you can press to select a menu item. Once on a call, it can also be used to adjust the phone volume. The right side houses the power button, camera activation key, and stylus, while the microSD expansion slot and mini USB port are found on the bottom of the unit. The camera lens (no self-portrait mirror or flash) is located on the back along with speaker and external GPS jack, and the SIM card holder is actually on the backside of the front cover when slid out rather than behind the battery. Speaking of which, a minor point, but we found it extremely difficult to take off the battery cover. There doesn't seem to be a release switch, so we had to pry it off with a sharp-edged object. Another thing on our wish list is a 3.5-millimeter headphone jack.

The AT&T Tilt measures 4.4 inches long by 2.3 inches wide by 0.7 inch deep and weighs 6.1 ounces. We're not even going to lie; the handset is definitely bulky and heavy, so it won't easily slip into a pants pocket. However, we think HTC did a nice job designing the Tilt. The smartphone has nice rounded corners and boasts a sleek-black-lacquer-and-polished-steel finish on front, while the back features a soft-touch finish for better gripping. It's more comfortable to hold than the AT&T 8525 and Sprint Mogul, and feels like it has a more solid construction.

Features
With the barrage of smartphones that hit AT&T's lineup this year, it caught us by surprise that this is actually the carrier's first Windows Mobile 6 smartphone. It runs the Professional Edition, and the updated operating system brings a number of small but notable improvements over Windows Mobile 5. For example, there's a new Calendar ribbon that gives you a better view of your schedule at a glance with colored blocks for appointments and details of the event, such as meeting location, right along the bottom of your screen so you don't have to open each one. There's also a new e-mail search function that works like the Smart Dial feature on Windows Mobile 5 devices, where you start typing in a word while in your Inbox, and it will automatically pull up messages with that term in the subject or contact field. We won't run through every new feature here, but you can read all about them in our review of Windows Mobile 6.

As a mobile professional's tool, the Tilt comes with the full Microsoft Mobile Office Suite for creating, viewing, and editing Word, Excel, and PowerPoint files. In addition, there's an Adobe Reader client for opening PDFs. Other PIM tools include a calculator, a clock, a ZIP manager, and a voice recorder. To manage your memory and optimize the device's performance, you can view the amount of available memory under the Settings menu and stop running programs with the Task Manager. The Tilt comes with 256MB of ROM and 128MB SDRAM. There's about 87MB of user-accessible storage and 68MB of program memory, and you can always expand the capacity by using the microSD expansion slot, which accepts up to 4GB cards.

Of course, with the full QWERTY keyboard, e-mail and messaging is also a key feature. The AT&T Tilt ships with Microsoft's Direct Push technology out of the box so you get real-time e-mail delivery and automatic synchronization with your Outlook calendar, tasks, and contacts via Exchange Server. In addition, the Tilt works with other e-mail solutions, including BlackBerry Connect and AT&T Xpress Mail. There is, of course, continued support for POP3 and IMAP accounts, but now you also can view e-mails in their original HTML format, regardless of account type. The Tilt also comes preloaded with AOL, Windows Live, and Yahoo instant-messaging clients and supports text and multimedia messaging.

For voice communication, the Tilt offers world roaming capabilities, a speakerphone, and voice commands and dialing. The Tilt's contact list is limited only by the available memory (the SIM card holds an additional 250 contacts) and is quite robust. You can store up to 12 numbers for a single entry as well as home and work addresses, an e-mail address, an IM screen name, birthday, spouse's name, and more. For caller ID purposes, you can pair a contact with a photo, a caller group, or one of 26 polyphonic ringtones. The Tilt also supports AT&T's push-to-talk service, allowing you to instantly see the availability of your contacts before calling them and make individual or group PTT calls. PTT plans start at $9.99 per month.

Much to our delight, and we imagine yours as well, the AT&T Tilt offers the full gamut of wireless options: Wi-Fi (802.11b/g), Bluetooth 2.0, UMTS/HSDPA, and GPS. The smartphone supports a number of Bluetooth profiles, including those for wireless headsets, hands-free kits, dial-up networking, and A2DP for stereo Bluetooth headsets. For surfing the Web, you can use the built-in Wi-Fi to hop onto a hot spot, or, alternatively, you can take advantage of the 3G support to get data speeds of around 400Kbps to 700Kbps (with the potential to hit up to 2Mbps) using AT&T's network. In addition, you'll be able to access UMTS/HSDPA networks while abroad. For your convenience, there's a Wireless Manager where you can turn on and off all the various radios.

With the built-in GPS radio, you can use a location-based service, such as AT&T's TeleNav GPS Navigator, and you can get color maps and text- and voice-guided driving directions, and points of interest right on the device. In addition, the TeleNav application can help you find the cheapest gas based on your location, share addresses with your contacts, and more. Just be aware that if you choose TeleNav GPS Navigator, this is an add-on service from AT&T that will cost $9.99 per month for unlimited trips or $5.99 for up to 10 trips; check out our full review of TeleNav for more information.

To get the most out of 3G, the Tilt supports the AT&T Video and AT&T MusicThe Daily Show, MTV Mobile, ESPN sports highlights, and a few other videos. Downloads were speedy with barely any delay for video buffering. AT&T Music is a full-featured service that not only allows you to purchase songs from independent music services, such as Napster to Go and Yahoo Music, but also includes streaming XM satellite radio, music videos, MusicID for identifying song titles and artists, and a music news site called TheBuzz. Unfortunately, not all features of the service were enabled on our review unit, but we were able to listen to XM satellite radio and enjoyed smooth streaming audio. Of course, you can import your personal library of MP3, AAC, WAV, WMA, MPEG-4, and WMV files via microSD card, thanks to Windows Media Player 10 Mobile. services.
