Building on the success of the BlackBerry 8800, the new 8820 adds several improvements to a familiar design. The BlackBerry 8820 is the first device from Research In Motion (RIM) to include built-in Wi-Fi, and includes the same built-in multimedia, memory expansion, web browsing and instant messaging capabilities that have defined the latest batch of BlackBerry smartphones.

Other features include a QWERTY keyboard, an onboard GPS receiver with BlackBerry Maps, Bluetooth peer-to-peer wireless and the popular BlackBerry Push E-Mail system. The BlackBerry 8820 is compatible with EDGE data networks, but lacks faster HSDPA connectivity.
The BlackBerry 8820 is now available from AT&T Mobile. Whether the 8820 will be offered by T-Mobile remains unclear.
