I'm having a very frustrating problem with my phone. I've been noticing a large number of random reboots lately. It primarily happens while I'm listing to music through my bluetooth headphones or my car stereo (connected via bluetooth). When the phone restarts it can't start the bluetooth and I get a force close of a system process. I have to pull the battery and cold boot it to get bluetooth back. Bad hardware? Time for a trip to Verizon?
