my friend is selling me his iphone 4, he is on 4.0.1 and wants to wipe out all his personal data himself before he hands me the phone , he does not undestand jailbreaking or unlocking.
can some one please help me with what he need to do in order for it to stay on 4.0.1 and unlock-able and wipe all his data off the phone .
thanks
