With the release of iOS 5.0.1 Beta, iPhone Dev team has also updated its Redsn0w tool to support this new firmware. Redsn0w 0.9.9b8 software doesn’t bring any new jailbreak for iDevice users, so don’t update your iPhone to iOS 5 if you care about the unlock.
iPhone Dev team has suggested some guidelines for third party application developers. Please read them below -
redsn0w version 0.9.9b8 will natively recognize the 5.0.1 beta that Apple let developers start testing this week (so you don’t have to play the “point at 5.0 IPSW” trick). Because the IPSW isn’t public, you’ll still need to provide it once to redsn0w (at which point it will cache all the important pieces so you don’t need to select it again).
For those 3GS and i4 users who preserve their baseband, the Mac version can also produce the NO_BB_* custom IPSWs for 5.0.1. (But please note that ultrasn0w doesn’t get updated for betas like this.)
This is still a tethered jailbreak for all except old-bootrom 3GS users.
For those are eagerly waiting for iOS 5 untethered jailbreak, check these details.
