The wonderful BlackBerry 8800 has had a nice run of exclusivity on AT&T for the last couple of months, but will now also be available on T-Mobile starting on Monday April 23. The T-Mobile branded version will bring support for myFaves, EDGE data, web browsing, a media player, GPS, and of course that full QWERTY keyboard goodness! The BlackBerry 8800 should be initially available online, and then through T-Mobile stores.
