IPhonewhite screen and lock button broken?

My iPhone 4S was dropped on the floor by my boyfriend now it's a white screen and I can't do anything. When I plug it into iTunes I can't access it because I have a pass lock on it. Which I can't unlock and I can't hard reboot because my lock Button is broken, Any help?

You're out of luck and the phone has to be replaced. Best to go to an Apple retail store and if you have it replaced through phone support do not allude to that it was dropped.
