Not sure why I missed this back at the beginning of the month, but according to TBG’s tipsters, T-Mobile USA is all set to launch its version of the BlackBerry 8820 on March 5th. While functionally identical to the 8820 on AT&T, the T-Mobile version will be suitably fettled to support the carrier’s new Hotspot @Home service.  It’ll be interesting to see whether RIM’s recent network outages will affect customers desire to pick up this cameraless handset.
