UNLOCK iPHONE 4 04.11.08 BASEBAND iOS 5.1
THIS GUIDE ONLY FOR iPHONE 4 AT&T:
Step 1: The first thing you will need to do is actually grab your iPhone, go to Settings > General > About and from this page write down your IMEI number.
Step 2: With your IMEI number handy you will need to head on over to AT&T’s online chat support page by clicking here. You will then need to login to your account, and then click the Chat Now link next to technical support.
Step 3: When you begin talking to an AT&T representative you will simply need to tell them that you would like to unlock your out of contract iPhone. Additionally, you will also need to give them your IMEI number which you wrote down earlier. When the AT&T representative has this information he will be able to determine if you are eligible for the free unlock.
Step 4: If all goes well you will be asked for your email address so they can send you more details about how to proceed in about a week or so when your unlock request goes through. From here you will simply need to wait it out until you receive a follow-up email that will include further instructions.
Done! If you have any further questions to do with the unlocking process or would like to share your thoughts about your experience please turn your attention to the comments section below…
