if you view the contents of the iPod... say with resorcerer, you will see an invisible folder iPod_control
inside there are iPod settings / device settings / music files
however the actual OS is hardwired into the iPod there is no way to get to it. It's not like a "system folder" on a disk for the Mac OS.
Good luck trying to get that shit off the updater.
Maybe try going dumpster diving at Pixo's headquarters? =)
