Started to panic this morning! I set the phone to go off from midnight til 6:00 AM and it always comes back on. Last night I wasn't so lucky! The phone went off at midnight like it was supposed to but when I got up this morning at 6:30 the phone was STILL off. Pushing the power button still didn't turn it on so I took the battery out and put it back in and it STILL stayed off! I had to take the battery out 3 times before it finally came back on. I really hope that wasn't caused by the update because having a phone that won't power on is NOT an option! I think I'm gonna call Sprint about that one today!
And I wanted to add that the battery was fully charged since I put it on the charger overnight every night while it's off!
