@geohot did it again! in a video that meets @Musclenerd strict standards. This works with the newest 3gs as well as all iPod Touches we’ve seen thus far. no release date yet, but we’d expect it after the upcoming hardware and software updates. 3.2 or 4.0? iPad or new iPhone. we’ll just have to wait and see.

UPDATE 3
closer inspection of the spirit exploit, not a bootrom exploit. The title was wrong. Still no 359.3.2 exploit.

UPDATE 4
finally goes down with the release of limera1n.  (limera1n-on-our-parade)
