when i woke up this morning my iphone displayed a notificaton saying calls and texts are unavailable please restore to fix - or something of the sort. but now, i have tried restoring the phone several times and on iTunes i get a message saying ''there is a problem with your iphone. it may be damaged and cannot be activated for service'' anyone know what i can do? i havent heard or seeen this problem before and like most people need my mobile phone, and as i am on holiday i cant get to the apple store till wednesday.
so you are saying if i go to the O2 shop, get a microsim then attempt to restore it will work?
if yr iphone is locked to O2 then giffgaff sim should be able to activate yr iphone, try DFU mode as other OP said, if not then thry any O2 sim.
