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.

Update

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.

do you think that jailbreaking/unlocking will solve the issue? have reloaded with iOS 3.1.2 just in case

i don't think that this is a software related issue, but to be honest - an non jailbreaked iphone/ipod touch or apple tv is like driving a sportscar with handbrake half pulled - so get it done and we'll try to find a way to get this job done

am having real trouble trying to jailbreak/unlock-redsnow, follow instructions phone shuts down but no pineapple symbol/reboot. goes back to apple screen.

what guide are you using? still on 3.1.2? first of all, it's enough to do the jb. the unlock can be done with bootneuter

thats hard to tell - there are surely ways to re-wire the complete card reader - but that should be the last option and you can only do that with very scecific tools.

i would check the contacts again, if one of them is slightly bent - it could be enough to let the phone not recognize the sim card
