Well the jailbreak has been finished! The Private Dev Team is proud to present it's jailbreak tool known as Phoenix! It is only make only right now, and it is completely unknown whether or not a windows version can be made. It currently works on all A4 devices, the iPod Touch 3G, and iPhone 3GS (they say it also works on iPad 2, but not confirmed). Here's is a download link. The jailbreaking process is very simple, hit jailbreak, wait for recovery, hit semitether, and you should be good to go! And here's a link phyrrus9 thought was important to share.
