snowbreeze 2.8b1, a jailbreak tool for Windows, has now been updated by iH8sn0w to support  iOS 5 firmware, which was earlier jailbroken using redsnow only on Mac. The reason to use snowbreeze is that it is currently the only jailbreak tool for iOS 5 Beta which is available for Windows, and it will also preserve your old baseband so that you can unlock your iPhone in future using ultrasnow. Unfortunately, this is a tethered jailbreak, you have to connect your iDevice to a computer when powering it on to boot it into jailbroken state.
