NEW BB TOUCH PHONE
Otherwise you get to wait till T-mo does an official launch.
You don't want 22.214.171.124. It is buggy. I used the Orange Launched 4.5os and it seems to be working well. I'm using 126.96.36.199.
Once again, you can find plenty of links on pinstack. I also posted one in the AT&T forum here at Phonescoop.com titles Blackberry os 4.5.
