The iOS Maps app with 3D Flyover featured as a centerpiece of Appleís iOS 6 presentation at WWDC has been hacked on to the iPhone 4 by Anton Titkov. For reasons not made entirely clear, Apple controversially opted not to support the capability in its iOS 6 update in the slightly older iPhone with critics debating whether it was due to a hardware limitation. While the performance (of the still beta) appears acceptable, it does not load quite as quickly or smoothly as it does on the iPhone 4S as the embedded video shows.
