I have a friend who is trying to sync his wife's new iPhone to her iTunes on the same computer his is on and gets this error. Can anyone tell me what this error means and what might be done to fix it. thanks.
Correct me if I am wrong but you can have multiple libraries on one computer (one iTunes) these can e linked to different iTunes accounts. This helps with separating accounts, music, and apps for families with multiple devices and only one computer (one iTunes)
