i jbed my ipod n i downloaded semitether, so i rebooted it, shut off, turn on, it works, i slide to open, all my apps are white, i click them and they dont open, so i shut if off, put it in dfu mode, then booted tethered with redsn0w but didnt change the icons, but it made them clickable, so i put a theme on, no change, changed it back, no change, any ideas?
