I purchased an iPhone 4 from a friend with the intention of using it with Straight Talk and it needs to be restored first before I proceed to jailbreak it. However, it's asking to upgrade to IOS 6 and I'm fairly certain that I shouldn't go to 6 and should be on 5.1.1, correct? I've been reading various sources and am very confused as to where I need to start. I've read about SHSH "blobs" and how I need to save the blob I want to downgrade to, but I have no idea how to do that, since I can't "see" my iPhone yet. If there's a link I haven't seen yet that's very descriptive, I'd appreciate the help. I'm kind of the guinea pig on this first attempt as my wife is in the same boat and I'll be doing the same thing to her newly purchased iPhone 4. A huge thanks in advance.
