Hi there. I will be getting the new iPhone 5 this Friday and I am looking to sell my iPhone 4 on ebay. I want to sell it unlocked to help get the most money that I can. I sent my request in to AT&T for the unlock, but did not receive it until this evening after iOS 6 was already released. I want to be able to keep iOS 5.1.1 so jailbreaking is still an option for the buyer and apply the unlock. From what I am reading I need to plug my iPhone into iTunes and restore it which will unlock the phone. However, since iOS6 is now out I am worried that unlocking my phone and updating to iOS6 will go hand in hand. So after all of that my real question is can I unlock my phone through iTunes while staying on iOS 5.1.1? Any help will be much appreciated.
