Just got an iPhone 4 replaced by Apple in Louisville today. The phone worked great, and I was extremely excited about the replacement process. Got home, and restored as new phone, and then updated to 4.0.1. Once the update was complete, I walked over to turn it on to unlock the screen. Didn't turn on, held the bottom button. Didn't turn on. Held both buttons, did not turn on. It looks like the screen is on, i can see a change in color in the lcd. phone makes all noises when restarting in itunes, and syncing, but no response in getting the screen on. Any ideas?
