iPhone screen not responding to touch and can't swipe to unlock I can't figure out why my iPhone 4s isn't working. The screen isn't picking up on my touch, I can't swipe to unlock. I can't turn the phone off as I have to unlock it first which obviously I can't. My guess is to leave it wait for the battery to drain out to force shutdown. 

My alarm is going off and will continue to snooze every 10 minutes until I swipe the phone to turn the alarm off, which as stated I can't. Any tips?
You can force the phone to restart by holding the lock and home buttons simultaneously for several seconds.
