Apple presented its new iOS 7.1.1 and some AT&T iPhone users have already updated to this firmware. You can easily unlock iOS 7.1.1 iPhone from AT&T in case you are still locked and limited to your 2-year contract or out of contract by now. AT&T official iPhone unlock is a simple, popular, safe, guaranteed, permanent and top-quality service that will satisfied all your desires within 24 hours or a few days.
Unlock for iPhone 5 / 5S / 5c / 4S / 4 AT&T is official because it is provided by listing your unique IMEI number [each smartphone has this number to be identified by the manufacturer] in the real Apple database of all IMEIs. Once your code appears in the unlocked section of this database you are officially unlocked.
You cannot do this on your own because you are unable to access this database. The companies that offer official unlock for AT&T iPhone models have this access as they work in partnership with carriers and Apple.
Unlocking needs IMEI which you can see after you call this simple number *#06# or search in Settings app – General menu – About section. If you want to be successful at the first attempt you should also use iPhone blacklist check and network checker. These two great services will tell you the original name of your carrier, activation and lock status along with blacklist status. After you make sure that your iOS 7.1.1 handset is really locked to AT&T, activated and not blacklisted / blocked you can order its factory AT&T IMEI iPhone unlock.
This is even easier to do.
Step 1. Enter IMEI number in the special field of the online order form.
Step 2. Enter email address as you are asked to do.
Step 3. Click Buy after you agree to Terms and Services.
Step 4. Pay for the service.
Step 5. Wait till you receive an email with a guide how to plug the smartphone to your computer, launch iTunes and complete the procedure.
This last step is required because iTunes also contacts Apple servers each time you connect. It will see that your new status is unlocked and finish unlock for your iPhone. From this moment you can insert different SIMs, including AT&T, Verizon, O2, Orange, Sprint, Vodafone and others.
