Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!). It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak. The 4.3.3 untether works on all devices that actually support 4.3.3 except for the iPad2:

- ultrasn0w unlockers must stay away from redsn0w! Use only a custom IPSW to update to 4.3.3, to avoid updating your baseband. There are plenty of tutorials for both redsn0w and PwnageTool at sites like iClarified.com. Or feel free to ask away in our comments section below.
- 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.
- 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.

Make certain you let iTunes upgrade you to 4.3.3 if you are not already. I was on 4.2.something and while I kept an eye on the instructions I thought I had bricked my 3GS. Thankfully I was capable to restore in iTunes
