I have a macbook pro coming tomorrow and i'm unsure what to do concerning my iTunes and my iPhone (yes, i realize this is NOT an iPhone forum but for the purposes of this post it serves the same function as an iPod). currently, i synchronize outlook contacts, outlook calendar, and a couple of playlists (i do NOT sync my computer's entire mp3 music collection) from my PC to my iPhone. I have backed up all my music to an ext HD which i will connect to my new MBP and then will transfer all the music to the MBP. also, once i get the MBP, I will import my calendar and contacts from PC to the MBP (iCal and iContacts - i think this is what they're called on mac). Now how do i go about connecting my iPhone to the MBP and syncing with it? Will iTunes erase all the data on my iPhone and replace it with data on my MBP or will I be able to keep the existing iPhone data and iTunes will recognize that i'm just switching to a new master sync computer? sorry! i'm new to mac and i'm confused about this process. thanks in advance for the replies! thanks!
