AT&T over the weekend began offering an unlocking solution for iPhone customers who have completed their contracts, according to an official statement from the carrier.

The carrier said that beginning April 8, it will offer qualifying customers the ability to unlock their AT&T iPhones. The only requirements are that a customer’s account must be in good standing and the device to be unlocked must not be associated with an active account.

Different from jailbreaking, which allows an iPhone to run third-party applications, an iPhone unlocking solution allows users to take their device to any GSM carrier network that supports the iPhone’s micro-SIM card.

Third-party iPhone unlocking solutions have been around for a while but are considered risky as they can result in permanent damage to the device if not done correctly.
