Since GB OTA update, I've had my phone restart itself a few times. Usually when I go to bed at night, I hit the power button and touch the Power Off option and put the phone down. Suddenly it restarts itself. This has happened about 4 times to me, once while trying to turn it off in a Movie Theater,which was really annoying. Never had this problem on Froyo. Does anybody else have this problem or know what to do to fix it?
