I changed the permissions on the CoreServices folder to 777 and I got the spinning ring of death. I haven't yet turned off my iPod and I set it back to 755. I still have SSH access however, my SSH turns off after a reboot because of a problem. Is it safe to reboot? EDIT: My iPod rebooted itself. Gonna hope I don't need to restore. EDIT 2: NVM. Rebooted into perfectly fine working state. Is there any way to change those permissions without having problems because I use MobileFinder to switch between different SystemVersion plists for convenience.
