Okay, so I am selling my iPhone 4 for an 4S I just bought (the 4S sucked through, waste of $800). I used the 'Reset all content and settings' that returns it to factory state, but now I see an apple logo with a empty white bar. I waited for 30 mins without anything happening. Problem is, no matter what I press the iPhone doesn't turn off. I tried holding the top and home buttons, I tried instructions to enter DFU mode, no dice. iTunes will not recognize it. Help?
