My Daughter picked up an iPhone 5S from Sprint the other day. She connected it to her laptop and upon first sync but get a message that it is synced with another library on a different PC. . This is where it gets weird. The message references a PC name that I use at work and that she has never been around. Her iPhone has never been plugged into any other PC. I thought that maybe there was some kind of a link between our apple ids but there isn't that I can tell. I'm completely confused.
