Well-known iOS hacker MuscleNerd has tweeted about how the current version of redsn0w, used to tether jailbreak iOS 5 beta 7, can also be used to jailbreak the golden master (GM) copy of iOS 5 seeded to developers earlier today. Typically, a GM version of iOS is the final version released to developers and doesn’t have any significant changes when released to the public.
MuscleNerd: redsn0w http://is.gd/6eek4Y can already tether JB 5.0GM (select beta7 IPSW for now though, til update)
