AT&T has just launched a new webpage that allows you to request a SIM unlock for an out of contract iPhone. AT&T has always made it reasonably difficult to unlock a device on its network but now it seems to be softening its approach and actually trying to make it easier for iPhone users. The form is fairly simple to fill in and if you meet a few simple requirements you can have your iPhone unlocked in 5-7 days.
To qualify for the free unlock from AT&T, you must either be a current AT&T customer or a former AT&T customer who can provide the phone number or account number of the account. The iPhone to be unlocked must have been designed for use on the AT&T network and all contract obligations must have been fulfilled. Also the iPhone in question must not have been reported lost or stolen.
AT&T will unlock up to five iPhones per year per account as long as the account is in good standing. Additionally, AT&T will also unlock any active and deployed member of the military who can provide AT&T with deployment verification; and purchased the iPhone from an authorized location at the "no commitment" price and can provide proof of purchase.
If you meet all of the criteria, you are good to go and can request an unlock online without the need to talk to anyone at AT&T customer service. Anyone with an out of contract iPhone 4 or iPhone 3GS considering selling to fund the iPhone 5 when it is released, should take advantage of this free service from AT&T. Having your device unlocked officially by AT&T will certainly increase its value and salability.
