Hi whether you want to unlock your iphone 4 from network lock then visit wickedunlock.com here they help you unlock your iphone using remote unlocking service.
Your phone must be jail broken and unlocked to use non AT&T
sim card. Be sure you have correctly installed redsn0w and ultrasn0w
unlocker. If you have recently updated your phone that will undo your
jailbreak and unlock. You will need to reapply them for the version of
your iPhone OS if they are available.
You are holding a locked handset. Find out from where you got it who it is locked to and get a hold of the unlock code from them normally around $50 from the Telco who locked it.
