UDID DeAnonymization — a developer exposed an API that connected UDID to other information such as Facebook ID. The API has been closed, but it remains true that your iPhone has a primary key and darn near every app developer has a database linking your UDID to other details about you. Apple requires this to not be public, but every private database is a bad architecture choice or security slipup away from being a public database.
