i just paid 575$ to get me an iphone 4 32gb off of craigslist he gave it to me everything was fine and now it is asking for a passcode i am guessing that he was being a **** and set it to ask after 5 hours of use or something cause all day it was working until i went to sleep and woke up is their any way i can get it off?
restore it if you dont know the passcode....no other way around it....hold power + home for 10 seconds, release power button continue holding home button until iTunes pops the message up that you're in DFU, then just restore it. It's that simple=)
