Last night Apple officially launched iOS beta 5 4 and today the Dev Team comes with an update for the redsn0w program so that version 0.9.8 beta 4 is available and allows us to jailbreak the new iOS 5 beta 4. Of course we are talking about a tethered jailbreak since only the bootrom exploit from limera1n can still do this on iOS 5 and an untethered exploit will most certainly be available only after the official release of iOS 5. This version of redsn0w works with almost all iDevices that can install iOS 5 beta, the only exception is of course the tablet iPad 2 for which there is no bootrom exploit.
You can download redsn0w 0.9.8 beta 4 from here: Windows, Mac. The jailbreak process is identical to that of here just select iOS 5 beta 4 instead of beta 3.
