So today i had my phone in my pocket, nothing else was in there and i took it out and theres a dent rite by the sleep wake button. and the button is stuck down forcing the phone to shut on and off not even getting to my home screen. but when it is plugged in it stays on. what should i do? my phone already has a crack in the screen. will apple replace it??? HELP?? it is an "original" iphone
