If you are on T-Mobile and having connection problems, please check your APN settings in Options > Advanced > TCP. The value for APN should be wap.voicestream.com. This is normally set from the carrier when you get your phone, but it apparently can be wiped if you update the OS of the phone. After you make this change, restart Slacker and you should be good to go.
Please note, that if you are connected to a BES, you may still have an IT policy pushed to your phone may not allow you to use Slacker for streaming. If you are connected to a BES, please contact your BES administrator to find out if Slacker is being blocked.
