On schedule, T-Mobile USA has launched another HotSpot@Home compatible smartphone – the BlackBerry 8820 from Research In Motion. The Wi-Fi-enabled 8820 is an update to the carrier’s 8800 and 8830 BlackBerry handsets. Although the 8820 is not exactly new, it has been available from AT&T for a few months. It adds another option for those looking to take advantage of T-Mobile’s VoIP offering.

Along with 802.11, the 8820 includes a MicroSD expansion slot, Bluetooth, GPS and the BlackBerry e-mail service. The handset, however, does not include a camera.

The 8820 is available starting today from T-Mobile USA.
