Forgive me for asking this because I am sure everyone creates new threads, but I swear I searched around for a long time and am more confused now than when I started... I have an iPhone 3GS that I bought new and haven't upgraded anything yet. I'd like to get iOS4 on it, but I don't want to lose the ability to unlock it. I currently have iOS 3.0.1 and baseband 4.26.08. I also have an older version of iTunes (220.127.116.11) What is the best plan of action here? How can I get iOS4 and keep my old baseband to unlock it? Jailbreak would be nice too while I am at it... Thanks in advance - I appreciate the help!
