AT&T now provides a way to unlock AT&T branded iPhones for free. There are several ways to do so such as calling AT&T customer care, emailing AT&T customer service. But I found the method below is most convenient to do so.
- Find out the imei of the iphone in General -> Settings -> About.
- Go to the AT&T link and fill out the unlock request form. You do not necessarily need to be AT&T customer. unless you are current or previous customer of AT&T, you will need to email AT&T a copy of the purchase receipt.
- AT&T will email you instructions to unlock the form in several days.
- Check the lock status of the iPhone here or here to verify that the phone is unlocked.
Sometimes AT&T will send you an email indicating the phone cannot be unlocked, it is because that the iphone may have been reported lost or stolen. AT&T no longer requires the contract commitments on the phone to be fulfilled, however.
