Mix Up w/Apple IDs
I was trying to help out my girl with her iPhone that had to be replaced. I was told I could back up her phone on my Mac. We came back from the Apple store and back up her iPhone. When we returned from the store with her replacement iPhone, I went to do a restore on her phone and somehow her phone became mine. Now when she downloads something it is on my account, and she needs my password to download. How do I remove her phone from my account and get her phone back on her account?
iPhone 5, iOS 8.4
