I recently updated my 8310 (AT&T) to the 4.5.110 OS. Post-update I cannot keep a call for more than 30 seconds. The phone apparently loses signal and disconnects. I get messages/e-mail/etc. fine and calls come through, but whether I'm making the call or getting it I can't keep it for more than 30-90 seconds. I know this is due to the upgrade, because it started as soon as I did the upgrade. I live in downtown Miami, so it's not as if I'm out in the boonys. Anyone have any idea how to fix this?
