The advertising identifier does not change on every call.

Using "CFUUIDCreate" IS WRONG, though. It generates a GUID. That's what CFUUIDCreate is supposed to do. But it's the wrong method to call to get the advertising identifier.

You get the advertising identifier from ASIdentifierManager, and it does not change unless the user resets it.

That's what I get for informing others of something I hadn't actually confirmed. Thanks for the correction. :)
