The only thing that you will do is just reboot your ipod, because redsn0w will not modify the system files. It crashes on "Updating ramdisk" and that's before it installs cydia or anything like that. It will NOT work. Wait for pois0n, that's the jailbreak for all iDevices with 3.1 or 3.1.1 on them. Including 3G iPod touch. So stop with "3.1 jailbroken-3.0 IPSW" it will just not work. You're just wasting your time.
