The Dev Team just released an updated version of redsn0w, version 0.9.6 beta 2 as the name implies, the version is not a finished product yet, but it should do the trick for most jailbreaking junkies out there.
The release of redsn0w 0.9.6 beta 2, aka Halloween redsn0w, was announced by MuscleNerd via Twitter over the weekend, and leverages the limera1n exploit launched last month by Geohot, as well as the 24kpwn exploit, in order to jailbreak devices running iOS 4.2 beta.

For Windows users who have run redsn0w and chosen “Just enter pwned DFU mode right now”, your device is now completely vulnerable. Running iTunes and selecting a custom IPSW from PwnageTool (choose it by pressing Shift+Restore)….you’ve now convinced your device and iTunes to restore to a custom firmware. Congratulations!
If you are timid about software and running these programs…please just wait! Don’t jeopardize your carrier unlock for a firmware upgrade. Wait for even easier methods than this latest redsn0w release.
