Every Apple iPhone, iPod touch and iPad has a unique device ID number associated with it, known as a Unique Device ID (UDID). Apple's device ID is a 40-digit sequence of letters and numbers. Customers can access their device ID numbers in iTunes or by downloading a free app from the Apple App Store.
A user can use an Apple ID and password to sign into the iTunes Store or App Store to buy content or authorize items the user has purchased. The ID is the proof of ownership for the content the user has previously downloaded from Apple digital stores. The Apple ID allows the user to re-download their purchased content for any of their devices. For iTunes on computers, an Apple ID is authorized to copy purchased content on up to 5 computers at a time.
