Unlock AT&T iPhone 5 [5c, 5S] Updated to iOS 7.1 Version
Apple releases new firmware versions and changes unlock methods. Older tools stop supporting the latest OS. Developers and companies keep finding working solutions to offer Apple customers fast and reliable unlocks for latest operating system and current iDevice models.
If you wish to unlock AT&T iPhone 5, 5c, 5S on iOS 7.1 you can now choose between two methods: factory unlock and R-SIM card unlock. Other methods can’t be applied these days. They simply don’t support iOS 7.1 and these smartphones.
R-SIM is the SIM card you insert into your iPhone 5 / 5S / 5c in order to unlock it. This tool supports iOS 7.x firmware and can unlock your AT&T handset with no problems. It should be purchased through the official R-SIM Chinese site. The price is not too expensive. It is also easy to use and fast to work. The instructions are easy to follow and understand, so you should be quick with unlocking via this method. It also doesn’t void Apple warranty which is a huge plus for selecting R-SIM for iPhone unlock which is not permanent, we should note.
Factory IMEI unlocking service for AT&T iPhone is a distant service that is also fast, reliable and safe to order. It saves your warranty and makes your permanently unlocked. Once you order it you will be always able to restore, install iOS versions and update basebands without becoming re-locked ever again. Such advantage makes factory unlock method similar to never-locked and SIM-free iPhones sold by Apple at very high price. Unlock is affordable and all you have to know is your IMEI code, activation status, carrier name and blacklist state of your device.
These are two main and only methods for official AT&T iPhone 5 iOS 7.1 unlock. They also support iPhone 5c and 5S handsets.
