Ive got here a black 16GB iphone 4 which is faulty/no service the front screen is cracked (just the glass, doesnt affect the screen working at all, works perfect) and there is small crack on the back aswell - i know these can easily be fixed too! The phone would work abroad no problem at all 100 ono? cheers
