Me and my wife have i phones and every time we add a new contact or change one it syncs to the other. How do we stop that from happening?
It's because you both have the same apple ID. Your iTunes accounts on your computer area the same account. Call apple for more help (:
Same with me and my sister's tablet. So change the id on Apple.
Change the apple ID.
