As we reported over the weekend, AT&T has gone ahead and allowed for iPhone 4S users who have already fulfilled their term contracts and their accounts are currently in good standing. So if this sounds like you then here are the steps to get your iPhone 4S unlocked.
How to unlock your AT&T iPhone 4S
First get the IMEI (International Mobile Equipment Identity) of your iPhone 4S. It can be found in Settings > General > About on your device.
Second, call AT&T or use their online chat and given them the number, saying you wish to unlock your iPhone 4S. They will then do a check on your account status.
You will then receive an e-mail from AT&T with instructions on how to finish the unlocking but it basically requires you to connect your iPhone 4S to iTunes and do a restore. Unfortunately, if you had jailbroken your iPhone 4S, you will need to redo this after the restore.
So if you’re up to it, go ahead and unlock your iPhone 4S before AT&T has a change of heart.
