I have a similar question, so I'll post it here. I have a pc that has all my media (music, vids, etc) and I sync my iPod and iPhone to it. I also have a MacBook Pro, which I use mainly for writing music (home studio). I just got an iPhone and spent some time consolidating all my contact info (from work, home, online, etc) and I'm loving having it all in one place finally. I mainly use my iPhone now to manage those contacts since I love playing with it. The Windows Address Book program is just okay - I'd rather use the Address Book in my mac laptop, but I'm kinda stuck syncing with my pc.
Is there any way to easily keep my mac Address Book in sync with either my iPhone contacts or my Windows Address Book? I do have a wireless network that the two computers can share files over. I'm thinking the only way would be for my to sync my iPhone with my pc so that it has the latest and then export the contacts from my Windows Address Book as vcards which I think my mac Address Book can import. Or is there another way? Use my mac iTunes to sync just the contacts from the iPhone to my mac Address Book? Thanks!
