A few weeks ago we reported on the new untethered jailbreak for the iPhone 4S and iPad 2, Greenpois0n Absinthe. Today, they offer an update with some bug fixes. Most of these fixes seem to be with the actual jailbreaking process itself and not with the phone. So if you’re already jailbroken, its probably not necessary to re-jailbreak.

The update does the following:
– Mac: added support for OSX 10.5, PPC and Intel CPU
– Added consistency check on startup to make sure required files are in place
– Windows: fixed bug in payload generator that might cause a crash
