From NeverBored Studios:
------------------ IMPORTANT NOTES: -You will need the iPhone 3GS to play Ghost Hunt AR since this game makes heavy use of the built-in compass and camera to augment reality. -It is recommended that this game be played standing up in an open area with the iPhone 3GS camera pointed outwards from yourself (Trust us, you will want to be on your guard when the ghosts start coming in waves). ------------------
