Two nights ago I was talking to a friend, when we hung up my phone just went dead! Could not turn it back on so I had to take the battery out and then turn it on. When it came back on it said I had 100 text messages! It was all my old ones!? Last night I tried to turn if off and it didn't want to shut off! Took the battery out again and it turned on, but I had to shut if off and it did that just fine this time. When I turned it on I had 100 text messages again!? all old stuff.....happen to anybody else?
