is it possible for me to sync both an iPhone and an iPod using my iTunes (on my mac) - or is the iTunes limited only to one 'unit' (either an iPhone or iPod)? i've got both- and I'd rather have both my iPhone & my Ipod have the same music, same data, etc etc. ideally- both should be synced so whatever changes I make on iTunes are also made on both. thanks in advance. btw- i did the search, but there wasn't any topic/thread that would've answered the question.
