My son used my iphone for the first time to put music on it. Now all of my information, pictures, contacts etc are gone. My iphone number comes up in itunes as his iphone. How do I recover my iphone infromation.
do you have a backup?
You can only sync to one computer, one iTunes library.
If you try to sync to another, you get a warning that all content will be wiped and replaced.
You ignore that warning and your situation occurs.
If you do not have a backup-on a computer or iCloud-your stuff is gone.
