repaired broken screen/lcd now says no sim
have repaired screen, put in DFU, installed itunes but now iphone wont recognise SIM. iphone is in uk, have tried o2 and 3 but no luck. what to do? have cleaned and checked SIM tray/pins. phone innards cleaned with isopropyl alcohol-can't find obvious damage to motherboard.
after much taking apart, cleaning, reseating all connectors-tried cleaning sim tray and easing pins up- reassemble and hey presto! working iphone. thanks lots and lots.
Is this a good question?
