Ok so I'm sure that everyone has watched musclenerd's new video about 2.2.1. He said that all iPod touch 2G users have the go-ahead to update, but did the dev team consider that maybe apple knows about the exploit to reach an untethered jailbreak (if there is one) and patched it with the update? Is this possible? If so then I think this is a very likely possibility. Apple knows their machine batter than anyone so if they know about a possible exploit then they have every reason to patch it.
