While Sn0wbreeze 2.2 for Windows has yet to come out, according to a very recent Twitter update, Sn0wbreeze 2.2 will let you play the ever so famous Pac-Man game while Sn0wbreeze 2.2 cooks the custom IPSW for your iPhone, iPad or iPod touch.
Sn0wbreeze serves the exact same purpose that PwnageTool does on the Mac, creating custom IPSWs without upgrading the baseband, but on Windows PC.
The best thing about Sn0wbreeze 2.2 is that it comes with a new Baseband Preservation Mode which will allow iPhone 4, 3GS and 3G users to easily upgrade to iOS 4.2.1 without upgrading their baseband, so that an unlock is possible using the latest version of Ultrasn0w.
However, there is no final word as yet that indicates when Sn0wbreeze 2.2 for Windows will be released.
Regardless of that, we'll definitely report once new updates roll in.
