The Dev-Team releases PwnageTool 4.3.3 and Redsn0w 0.9.6rc15 for untethered IOS 4.3.3 Jailbreak

2. ultrasn0w has been updated to v1.2.3 to be compatible with iOS 4.3.3 and earlier (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.3.

3. By popular demand, redsn0w now allows you to enable multitasking gestures (although most will find it useful only on iPads).
iPad2 update: The iPad2 jailbreak remains under development. As you may know, the original exploit @comex developed in the first week of the iPad2 release was mysteriously fixed by Apple within days of its development. Partly because of this, don’t expect much public discussion of the iPad2 jailbreak until it’s actually finished and ready for release (and please avoid asking about it). In all liklihood, it will be a userland exploit like the first (unreleased) one, not dependent on bootrom dumps. The first one can’t be released even for those with the original 4.3 firmware due to legal (distribution) reasons.

4. Redns0w 0.9.6rc15 is available for Mac and Windows , while only PwnageTool 4.3.3 for Mac and temporarily only via torrent.
Soon comes a guide to run the jailbreak with the new firmware version
