The BlackRa1n jailbreak will work with the latest 3.1.2 firmware but not the latest 3.1.3 firmware.
For those with the new iPod touch or a new iPhone 3GS, BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it.
Ok lets begin...
Step One
Open your web browser of choice and navigate to http://www.blackra1n.com. Click the Windows logo at the bottom of the screen.
