Apple's in house mapping platform was announced at the WWDC, and they're going to be doing the cartography itself, instead of using Google Maps, kicking them to the curb.
The latest addition to it is the turn by turn navigation in iOS 6, which has been a big feature to look out for, and will be narrated by Siri.
It'll also have a 3D feature called Flyover—a "3D photographic model of cities all over the world." It's probably based on C3 Technologies tech, which is present in Nokia Maps, but Apple's version looks pretty great.
All of the maps are in vector graphics and there's an in-line card with reviews and ratings.
Knowing that they were getting divorced, Google themselves announced a ton of new mapping features last week, including offline maps, which Apple users might not see now.
