How does Apple know whom an inactive iPhone belongs to? I tried to log into my daughter's iMessage on an inactive iPhone. She called Apple because she got an email. They told her it was an iPhone 5c black. How did they know that? Do they know who the owner is? Is there a way to block my old iPhone so Apple can't trace it?
They store device information thats linked to the UDID of the device. As far as I know, they can't tell who the owner is for sure. Moreover, I also doubt you can block the old phone.
