Apple iPhone 4S Meets “Very Preliminary” Jailbreak
Maybe the semi-tethered jailbreak of iOS 5 will make the waiting a little bit more bearable but the goal for everyone is an untethered iPhone 4S jailbreak and the Dev Team has managed a preliminary, one.
MuscleNerd himself calls it “very preliminary” because there are “huge missing pieces” that currently “prevent public release. LOTS of work left” but the concept has been proven and the iPhone 4S (and the iPad 2 running iOS 5 for that matter) has been jailbroken.
