When I am out I always add new contacts on my phone when I meet new clients etc. My iMac has a different set of contacts contained in Address Book. When I sync, it wipes out my contacts on my iPhone and replaces them with those on iMAc. I want to keep them synced with same contacts, is there a way to do this without typing the new ones on iMac that I added on my iPhone? Software to sync these two databases?? Thanks!
