Last Friday, we reported that AT&T has released a statement stating that they will start unlocking iPhones. AT&T said that the unlocking service will only apply to off-contract iPhones and to members who have AT&T accounts in good standing.
Today AppleInsider, reports that the unlock codes are applied to the device after restoring through iTunes. The unlock code comes through Apple and is released via iTunes.
AT&T’s instructions tell users to open iTunes on their Mac or PC, connect their iPhone via USB, and backup and restore their handset. The restore will then allow the iPhone for use on other carriers.
In addition, AT&T’s instructions have also been published on Apple’s website. If the unlock is successful, a message on the iPhone is displayed that says: “Unlock Complete. Congratulations, your iPhone has been unlocked. To set up and sync this iPhone, click Continue.”
