Sn0wbreeze developer iH8sn0w has released Sn0wbreeze 2.2 for creating iOS 4.2.1 custom firmware and now is available for download. Sn0wbreeze 2.2 is also known as PwnageTool for Windows. Well, just like the PwnageTool released for Mac, the Sn0wbreeze 2.2 also incorporates the kernel based GreenPois0n exploit for untethered iOS 4.2.1 jailbreak.
The highlight feature of Sn0wbreeze 2.2 is the new “Baseband Preservation Mode”. This new mode enables current iPhone 4, 3GS and 3G users to preserve their baseband while upgrading to iOS 4.2.1 so that they can unlock using existing version of Ultrasn0w.
Also new in Sn0wbreeze 2.2 is the ability to play Pac-Man game to keep you busy while the custom IPSW is being built for your iPhone, iPad or iPod touch, along with the ability to change boot logos, thanks to GreenPois0n RC5/6 exploit. Fix for iBooks is also included.
Sn0wbreeze 2.2 supported devices are;
* iPhone 4, 3GS, 3G
* iPod touch 4G, 3G, 2G
