I am about to get a new iphone from my apple store so I need to back up my contacts. When I try to sync my phone to save my iphone contacts in my address book it says it will add 137 and delete 15. I hit cancel because I dont want 15 contacts to get deleted I want to save all my contacts so when I get my new iphone I can just sync and have my contacts back. I cant afford to loose 15 contacts because they might be important contacts. Any suggestions?
