Sn0wbreeze, the PwnageTool alternative, is now upgraded to Sn0wbreeeze 2.2. The tool is expected to support iOS 4.2.1 jailbreak, but we haven’t received any official word from the hacker yet.
However, the hacker has included new feature in Sn0wbreeze 2.2, which will help users preserve their iDevice baseband value. With baseband preservation mode, you don’t have to worry about future jailbreak. The previously saved SHSH blobs will make things easier for you. Have a look at the screenshot of new Sn0wbreeze 2.2 tool.

For those who don’t know, you can also save your SHSH blobs using TinyUmbrella tool.
