There’s a hacked up version of quickpwn 2.2.1 going around. This is basically just quickpwn 2.2 with a hacked up bundle added to it by a 3rd party. This is not the official quickpwn 2.2.1. The official version is actually still being tested. The dev teams prefer to release tested software rather than untested software. Still, if you are interested in trying it out early and are totally fine with having unstable, unknown, untested software, you can try it out from here. This only has 2g bundles so if you have an iPod or iPhone 3g, you need to wait.
