Looks like the main jailbreak devs talked to each other today to release their jailbreak tools altogether around the same time. About an hour after the Dev Team announced the release of their PwnageTool jailbreak for iPhone 4.2.1, and now iH8Sn0w is releasing Sn0wBreeze 2.2.

Just like PwnageTool, Sn0wBreeze is a jailbreak tool that allows you to update your iPhone to the latest firmware, and jailbreak while preserving your baseband and your ability to unlock

PwnageTool is Mac only and Sn0wBreeze is Windows only. You can download Sn0wBreeze from our iPhone downloads section.
