In order to limit customer confusion or misunderstanding, Apple has posted a list detailing the international regional availability of certain features of iOS 6. Certain functions like Siri, the new Maps app with 3D Flyovers and turn-by-turn navigation are not available in all locations where the new iPhone 5 will be sold. With Apple dropping Google Maps, it has had to sign numerous international agreements with map suppliers, where available, in order to gradually add 3D and navigational functions, in particular.
