I've got a Motorola e815 from Verizon right now, and I've got no problem syncing it up with my iMac. I can edit the contacts in Address Book, and then the edits will get ported over. Whenever I add a contact in my phone, that will get added to Address Book after a sync. But does it work the other way around? Can I add a contact in Address Book, and have that added to my phone? I recently added a "Test McTest" in Address Book, and after a sync, that was not in my phone. My main point of asking this is to see whether I can use Address Book and iSync to completely port over my contacts to a new phone.
