Typically, the process of unlocking an AT&T iPhone is a lengthy one. Users have to fill out a form online, send AT&T a fax, and then wait around for a few days while everything processes. That is not the case with the AT&T iPhone 5 says TechCrunch.
Instead of a lengthy process, AT&T iPhone 5 owners who bought their phone off-contract only need to plug their device in and restore it through iTunes.

Doing this is simple.
1. First, plug in your iPhone.
2. Next, open up iTunes. You’ll need to be on the latest version which is version 10.7.
3. Then, click your AT&T iPhone 5 when it appears on the left-hand side. You’ll be taken to a screen that has the option you see below.
4. Hit the Restore button and afterwards, you should be greeted with a message that says: “Congratulations, your iPhone has been unlocked.” If you got that message, then you know your AT&T iPhone 5 is unlocked and ready for another carrier if you so desire.
Once complete, owners are free to slim down a Micro SIM card to fit inside the iPhone 5′s Nano SIM card slot. Owners can also wait until October to pick up a Nano SIM from T-Mobile itself.

The iPhone 5 will run on T-Mobile’s EDGE network in areas where it doesn’t have its new HSPA+ network set up and unfortunately, at this point, virtually everywhere is without it. However, the carrier is going to be making big strides in the future which should make an unlocked iPhone 5 more attractive.
Verizon’s iPhone 5 is a little different from AT&T’s in that it comes unlocked right off the bat, ready for T-Mobile or AT&T.
