Some jokingly refer to the 7210 as a BlueBerry rather than a BlackBerry because of its azure casing. A bit shorter and thicker (4.4 by 2.9 by 0.94 inches) than RIM's stalwart 957, the unit is compact for a smart phone; male buyers will probably wear it clipped to their belts using the included swiveling holster.

The high-resolution, 240x160-pixel color display supports 65,000 hues and is the same width but a shorter length than the 957's screen. Though not as bright--even with the backlight on--as the displays found on Pocket PCs or Palms, the screen is readable and is made for viewing in direct sunlight. As for the keys, they're slightly bigger and raised higher than the 957's, so they're more tactile. Either way, the 7210's minikeyboard is among the best available to date and certainly superior to the ones found on Handspring's Treo models.

The first thing you'll notice when you go to dial a number manually is that RIM has created a traditional number dial pad over the keys on the left side of the keyboard. When inputting numbers as part of a text message, you may be initially thrown off by the layout. However, the arrangement is essential if you want to dial numbers on the 7210 as you would with a traditional phone.

As with RIM's earlier combo units, you can plug in the bundled headset to make a call, but this model also features a built-in earpiece and mike. It's not the most comfortable implementation, but it's quite usable as a phone, a wireless e-mail device, and a PDA.

Along with the familiar scrollwheel and the Back button (which you press to end a call) on the right-hand side of the unit, you'll find a port for a USB cable/charger on the left. On top, there's a quick-launch button for phone mode, plus an IR port. The removable lithium-ion battery can be replaced.

While it has no SD (Secure Digital) card expansion slot, this model ships with a healthy 16MB of internal flash memory and 2MB of SRAM. The unit also includes a 10MB in-box, and it supports Lotus Notes. Yet the dual-band 7210, unlike T-Mobile's 7230, is not a true world phone (GSM 900/1900; GPRS).

If your company hasn't installed BlackBerry Enterprise Server, you can opt for BlackBerry Web Client, which comes in AT&T's package and allows you to have e-mail messages wirelessly forwarded to your 7210 from an e-mail account. Setup is fairly simple and can be done in a matter of minutes on the Web or via a wireless Web connection on the device. Data plans are $39.99 per month for 8MB of data or $49.99 for unlimited e-mail.

While the enterprise version offers real-time e-mail delivery and wireless calendar syncing (an appointment can be wirelessly updated from the office), the e-mail pushed to the 7210 by Web Client has about a 15-minute delay. And Web Client now offers some wireless syncing; if you delete e-mail on the 7210, it will also be deleted on your desktop. The BlackBerry's address and calendar applications aren't quite as snazzy as a Pocket PC's or a Palm's, but most users will be pleased with the device's PDA side. Other core electronic organizer applications include a task manager, a memo pad, a calculator, and an alarm. The BrickBreaker game comes preinstalled, and you can add third-party applications just like you would with a Palm or a Pocket PC.

With J2ME onboard, RIM is touting the BlackBerry's expansion into the Java realm, which is a plus. You can now open a wide variety of e-mail attachments--most importantly, Microsoft Word, Excel, and PowerPoint files, as well as Adobe PDFs--and view them on the device. Unfortunately, you can't edit a Word or Excel file, save it, and send it back to a colleague. This is a read-only situation.

Like other BlackBerrys, the 7210 is lacking in the multimedia department, but that's not a sin, especially as this is a business-oriented device. However, in an ideal world, we would like to have seen a speakerphone and Bluetooth support for wireless headsets.

All the phone basics are here, including a robust call history, the ability to dial contact numbers directly from the address book, two-way SMS messaging, and a vibrating ringer option. Phone and PDA elements are well integrated. A Web browser is onboard, though only Enterprise customers can currently surf full-blown HTML sites. RIM says a downloadable software update that adds HTML browsing will be available for Web Client users later this year.

You'd expect a color screen to have a serious impact on battery life, but the 7210's display is designed to use the backlight sparingly; you'll need to activate it in only dimly lit environments or at night. As a result, you can expect decent battery life that's on a par with that of the most energy-efficient smart phones currently available. RIM says you can get up to four hours of talk time and 10 days of standby time. In our tests, we hit the talk-time number and managed to go a full week on standby. With normal use, however, you should expect to recharge every third day, or every second day to be on the safe side.

Using AT&T's GSM/GPRS service in San Francisco, we had a generally good experience. Occasionally, we lost the sweet spot of the speaker on our ear and had to adjust the phone accordingly. Also, when the backlight was on, call quality diminished significantly. But the BlackBerry was fairly loud, and we appreciated that we could raise and lower the volume using the scrollwheel in the middle of a call. On their end, callers said we sounded clear with no static. In noisier environments, it helps to use a headset, but it's not essential.
