I have an unlocked blackberry storm 9530 running on AT&T and I updated it yesterday to 5.0 os and now the only thing that i can do is send and receive texts, what's the problem? When I try to make a call it says Congestion and then Disconnected, every time. Any suggestions? When downgraded back to 4.7 it works just fine..
