Does a tethered jailbreak for an iPhone 4S with iOS 5.0.1 exist? I have an iPhone 4 with iOS 5.0 that has been jailbroken. And, I would like to purchase a new iPhone 4S. But, I want to know beforehand whether or not, at least, a tethered jailbreak is available for the new iPhone 4S. Please advise. Thanks much.
