phone wont go passed apple logo
Boyfriend threw my iphone 4 out of anger, screen cracked obviously. phone wont turn on. if i connect it to the wall or laptop the apple logo pops up and then disappears. i haven't synced anything in over a year. I dont mind opening it up since i have replaced the screen before. what do i look for? my itunes wont detect my phone. can i still somehow get my data?
