I somehow lost all my contacts in my phone. When I last synched I guess it wiped out the contact on the computer also. Or vice versa. I guess I wasn't paying attention. Now the QUESTION:

My wife's phone has similar contacts, enough to get me started rebuilding mine. She has her own MAC. If I try to synch her contacts to my phone will I get them or delete hers? In other words, since synching contacts goes both ways, which way are changes made?
