IPhone asks to log in with a different Apple ID
I have two different Apple ID's on my iPhone.
I have purchased a new iPhone to replace my old one and I have used the back-up option to restore all the settings of the old one.
it now constantly asks me to log in with a different Apple ID that belongs to a friend. He has never logged in on my phone and my previous iPhone never asked for it.
The only exchange I had with him was copying some songs that I uploaded onto iTunes. I have deleted all of them but I still receive the same request.
Can anybody help me please?
