I downloaded Quab and ancient system. SSHed them into the correct folder using WinSCP, rebooted my iPod touch 2G 3.1.2, and went into winterboard and checked quab. Winterboard resprung my iPod, but there was no theme change (i had no theme before quab). I rebooted and tried Ancient system but it didn't work either. Other themes from cydia did. Whats wrong?
