I've been trying to sync the calendar from ICal and contacts to my 3rd gen Nano, but it doesn't work. In Itunes, it goes through the sync process but it doesn't show up on the IPod.
I'm trying the same thing and can't get it to work. I just got my nano today and it did have my calendars on it, but now it doesn't and when I sync it, it makes no difference... I have it set to sync all calendars.
