I just got off the phone with Blackberry and their tech confirmed the newest update (7100E_PBrER4.0.2_rel42_PL126.96.36.199_A188.8.131.52-REBUNDLE.exe) for T-Mobile users.
Fixes one perticular bug..... The rebooting bug. It fixes a issue with the radio he said. There are no other issues resolved with this upgrade. The upgrade doease not take anything away.
This is all from BB. I called Tmobile and they transferred me to the bb guys.
