I'm a little nervous about the possibility of losing my ipod with all my phone numbers in it, but it's definitely convenient to have SOME numbers in there that are non-personifiable (e.g., local taxi, restaurants, etc.) .. i figured out that basically anything that has something in the "company" field is safe to sync, for me -- so i made a smart group that looks for just that, and of course will update whenever i add more. but it doesn't show up in the list of 'groups' under the iPod preferences in itunes. is this a bug? anyone know of a workaround?
