itunes device name is different to same device name on find my iphone
I have a device on itunes which is named correctly.But when I look it up on "Find My Iphone" the device has a different name.To make matters more confusing it has the same name as another device owned by my daughter.How do I get the device name on "Find My Iphone" to match the device name on itunes?
Many thanks.
