I have a long list of work contacts I would like to add to my new iphone 4S. I would like to type them into my address book on my MBP with Lion and synch them over, WITHOUT affecting my existing contacts on the iphone. I have read a few threads on this and would like some clarification, I would not want to lose 500+ contacts already on my iphone that are not currently in my macbook address book. I do not want my current iphone contacts in my mbp address book only vice versa. Any tips on how to do this?
