How to upgrade and unlock my iphone to 5.1.1 and preserve the baseband
Currently my iPhone is running on version 4.3.3 (8J2) and firmware 4.10.01. I'm using a Gevey sim, but I want to unlock my phone the software way, but I also want to update my phone to version 5.1.1- Can anyone help me please! I vote best answer. Additionally, can you attach a video with instructions if you know where one is online?
