I have one Iphone 3GS with IOS version 6.1.3 which was jail broken and unlocked (not factory unlocked). My dad was using this phone and it was working fine, Phone stopped connecting to network recently and only thing he did was connecting to ICloud which he has never done earlier. Is there a chance that connecting to ICloud makes the phone locked again? I have tried network reset etc but couldnt resolve the issue. Wanted to check before i restore and do the unlock again.
