I have an iPhone and bought an iTouch for my daughter. I have the same Apple ID on both but have Facetime, Messageing, etc with a different e-mail addresses. However, when I deleted and renamed contacts in the contact list on her iTouch it deleted and renamed them on my iPhone as well. So I've lost a lot of contacts.
Question 1: how do I prevent this from happening
Question 2: Is there a way to get my contacts back.
