My iPhone 4 Randomly cut off and "connect to itunes" screen appeared
I was using twitter on my phone (EchoPhone) and then my phone cut off. It would not turn back on when I pushed the power button. I went to the car and plugged into the car charger and the connect to itunes screen appeared. This has happened to 3 people I know in the past week.
iPhone 4, iOS 5.0.1
