I got a 02 registered 3g Iphone from a friend. It needed unlocking so I could use with my Vodaphone sim and being not very techy I took it to one of these shops that unlock. She did it and it was fine. Then STUPIDLY i decided to ERASE ALL CONTENTS AND CLEAR because I read somewhere that this would clear all my friend info off the phone. It then froze after a hour on the apple logo and timer thing. So I plugged it into comp to try and restore through ITUNES. It gets almost to the end then is comes up UNKNOWN ERROR 1015. Please someone help is there anything I can do?? I'm not very technical so please be as gentle as possible. Thanks.
