Renowned iOS developer MuscleNerd has just sent out a tweet stating that RedSn0w 0.9.8b4 has been released as a tethered jailbreak solution for iOS 5 beta4.

We reported earlier today that Apple had seeded iOS 5 beta4 to developers, and that it was just a matter of time before it was jailbroken.

With the release of the iOS 5 beta3 jailbreak in mere hours after release, the community remained confident in the Dev Teams ability to push out a solution with a turn around time of under 24 hours. We will keep you updated on any further developments.
