If you are referring the Sirius XM Android app, it has been very buggy for me also. I believe it to be a problem between wifi and bluetooth. Runs fine on 3G or wifi, but if I turn Wifi and Bluetooth on at same time it freezes. If I then force close and restart I can only connect over Wifi, 3G no longer connects even with bluetooth off. I have tried wiping, restoring, other ROMs... it seems to me to be a problem with FRG83 (in my opinion).
