Update: This is an outdated and nonworking method of unlocking AT&T iPhones. AT&T has since released an easier official way of unlocking any device.
As you may already know, after five years of offering the iPhone, AT&T started unlocking iPhone for the first time on April 8. However, AT&T doesn’t unlock all iPhones, they have some requirements and one of those requirements is to have an AT&T account in good standing. This sounds like if you want AT&T to unlock your iPhone, you’d need to be an AT&T customer or have an online account with them. However, if you bought your iPhone off eBay, Craigslist, or another place and didn’t purchase it directly from AT&T and have never been an AT&T customer, it is likely that you don’t have an AT&T account.
Fortunately, there are a few loopholes that allow you to make AT&T unlock your iPhone, even if you have never been a customer with them or don’t have an AT&T account. The first loophole involves calling AT&T and speaking to a representative. The second is to chat with AT&T’s technical support online which doesn’t require an AT&T account. Both methods won’t require you to provide AT&T with your personal information such as phone number, address, or full real name. All you’ll need to provide AT&T is the iPhone’s IMEI number, a valid email address, and maybe your first name.
Unlock AT&T iPhone by calling AT&T
If you want to unlock your AT&T iPhone by calling AT&T, call AT&T at 1-800-331-0500. When calling, talk with a representative. Tell the representative that you want to unlock your iPhone. After that, the representative will ask you for the iPhone IMEI number which can be found by going to Settings> General> About> IMEI. Then she will ask you for your email address to send the unlock instructions.
Unlock iPhone on AT&T chat without an AT&T account
Luckily, a guy named Jason Hawks noticed that AT&T does not use a tech support system made by themselves, they use a third-party chat/customer support system by LivePerson. This makes it possible to chat with AT&T tech support without having an AT&T account by modifying the URL. Click the URL below to chat with AT&T tech support…
Explain to the representative that you want to unlock your iPhone. Then you should receive an email from AT&T like the one below. Restore your iPhone with iTunes and the iPhone should now be unlocked if AT&T approves the unlock request.
