it wont do anything i can turn the phone off and then go into say maps but i cant get out of it and go back to the main screen. if im in contacts it will call out and everything but wont go back to the main screen the phone is fine itself sometimes apps load up then it goes back to the main screen on its own. it asks for a password sometimes even though i dont have one. i tried restoring it and nothing works... any ideas? its a 16 gig 3g
