I upgraded to GB a month or so ago (download, not OTA). Nothing but problems since. Battery life is significantly less than before - less than a day, with minimal phone use, no BT, no WI-Fi, etc. before a need to recharge. Music player randomly stops playing and must be restarted. At times, the phone randomly reboots itself and after shut down, sometimes restarts itself. I did a wipe/reset yesterday and the reboot/self start issues seem to be resolved, but battery life and music player issues remain. Anyone else having these problems? I'm almost ready to go back to Froyo.
