We have pwnage. Before you get too excited, we're talking just iPod touch -- the update that's been around since Tuesday afternoon -- not for iPhone 2.1, released this morning. That having been said, point your browser over to quickpwn.com to grab the latest version of the iPod QuickPwn.
Now there is good news, and there is bad news, about jailbreak and iTunes 8. The bad news is that Apple has taken countermeasures against custom ipsw firmware bundles. The good news is that the iPhone devteam folks are working on patches for each of the device types in addition to the touch.
Hop over to the devteam blog to keep abreast of the latest news.
