How to unlock iPhone 3.1.3 firmware on baseband 05.11.07 (3G/3GS)

Unlocking the iPhone 3.1.3 on baseband 05.11.07, is a process that enables the use of any SIM cards on your smartphone. That means you can change your carrier and take advantage of your favorite pricing fees any time you want. Also, you can perform this process on any platform you want. It has been tested and found working for Windows and MAC too.

Before continuing to unlock the iPhone 3.1.3, you must know that this works only if your baseband is 05.11.07, the 3G and 3GS models. If you have an older baseband iPhone, with the same firmware, we have a guide for them too.

Keep in mind that if you unlock the iPhone 3.1.3 firmware, you will lose your warranty. Also, if you do not follow our steps carefully, you might end up with a bricked phone. Our method is tested but do not try it on a 05.12.01 baseband, it will not work.
