Ive been using iphone 3g for about 2 weeks. I went into sleep mode an hour ago and then I wanted to text someone but my iphone's screen wouldn't turn on even after hitting the home button or the lock button(You know how the screen turns on when you hit the lock/home button). The battery wasn't dead and I've never dropped it before nor did I jb it. Current FW 2.2.1. Did this happen to anyone else? I had to connect it to itunes to have the screen lit. Would this be a FW bug?
