While All of us were waiting for MuscleNerd to come back and give us gift of Redsn0w 0.9.8 beta 5 to jailbreak iOS 5 beta 5. At last the wait has been over and iPhone dev team has released the Redsn0w0.9.8 beta 5 to jailbreak all idevices on iOS 5 beta 5 except iPad 2. It is still a tethered jailbreaking tool and we personally think that even if iPhone dev team has found the vulnerability for untethered jailbreaking of iOS 5 beta 5, they will not be releasing it before the final version of iOS 5 arrives. Redsn0w 0.9.8 beta 5 is available for both Windows and MacOS X.
As is it a beta version and Apple release beta versions only for developers, so if you don’t have apple developer account then we would recommend you to stay away from the jailbreak as Apple has started the crackdown against the non developer users of the beta version.
