my son has just taken my lovely 2g which was looked after lovingly and updated it through itunes.It was jailbroken arrgggghhh and now of course everything is gone.All I get when I switch it on is the itunes symbol and a usb picture underneath it.I got it second hand already jailbroken with no sim.(I had it on vodaphone)Its saying insert sim but of course I dunno which network it was on.Do I buy a sim card from every network and try that or do you think it would be O2?? He thought he was being helpful *wails* please help a damsel in distress
