  • Untethered jailbreak for iPhone 4S IOS 5.1? I've heard such a thing doesn't exist. If that's the case, what should I do about jail breaking an iPhone 4S with ios 5.1? Should I somehow upgrade to 5.1.1 and do the untethered there? Or should I get the newest version apple has (probably not) and find or wait for a possible update for jail breaking there? And if I do somehow get an iOS 5.1.1 and manually update the phone to that, it won't mess anything up or erase my data, right?
