Hmm...where to start. A few days ago I plugged my iPod in to be charge/sync. I received an error message that my iPod "could not be read or written to". I called apple tech support and after about an hour of fussing around we were able to wipe the iPod and start over. After reloading all of my applications, songs, movies, etc., my calender (on the iPod) started duplicating appointments and jumbling up my calenders. I have rebooted my iPod, restored my iPod and wiped and redone my iPod. Same thing, nothing seems to be working. My iCal is correct and without errors, it just seems to be the crossover to the iPod thats messed up. Any suggestions?
