Right on schedule, T-Mobile USA has dropped the BlackBerry 8820. This Wi-Fi enabled handset sports GPS, a full QWERTY keyboard, microSD slot, and a whole lot more. Features-wise, this thing isn’t a whole lot different from the 8820 that dropped on AT&T last Fall, but with support for T-Mobile’s Hotspot@Home UMA calling service, we’re sure this appeal to more than a few of you out there. The phone is availbel right now from retail channels including t-mobile.com and most T-Mobile corporate stores. Expect to pay $349 with a 2-year contract.
