Just in case you didn’t find success with blackra1n or redsn0w tools, you can give Sn0wbreeze a try! Sn0wbreeze is fully compatible to work with Windows 7/Vista and XP machines.
It is very important to note that sn0wbreeze is still in public beta which means that it might have some issues. If you are new to jailbreaking, we don’t recommend sn0wbreeze for you. blackra1n and PwnageTool are still the recommended tools for jailbreaking iPhone and iPod touch.
