I've recently picked up a new MacBook, my iPhone was synced with my old iMac that I no longer have. I want to sync my iPhone with my new MacBook, will I lose my contacts if I do it? I know it says erases all data on the iPhone when I click sync, so I'm a bit worried about going through with it before backing up my contacts. If this is the case and I do need to save my contacts, what would be the best way to go about doing this? Any help is appreciated.
