Bought an iPhone a while ago. Had it unlocked to use on the 3 network. Now the thing is it used to freeze or flicker before I unlocked it, thought upgrading the firmware and then unlocking would sort that out. Well it did but now it does that again!
The thing is I note its on warranty for another 2 months! I might take it to the local shop but the thing is as it's been jailbroken and unlocked.. how would I restore it to Factory settings?
also this was bought of a well known auction site, would I need the original simcard of the previous person to activate the phone? once I restore it.
Thanks in advance guys!
