Just a heads up to those trying to jailbreak their iPod Touch 2G MB model device. I successfully jailbroke mine a few minutes ago, but used my desktop computer with Windows XP. I tried doing it with my laptop twice using different USB ports, which is running Windows 7, but didn't have any luck. Anyway, for those who are stuck on "waiting to reboot," try an older machine running XP. That might do the trick.
