'GunRange' Didn't Quite Blow Me Away
Almost every time Apple bolts a new gizmo to a new iPhone model, it backs it up with an application built into iOS. For example, when the 3GS came out last year, it came with a video camera and a magnetometer. So video editing software and a compass app came with it, rolled right into the OS. Other apps came along to use that hardware as well, and sometimes they made more extensive use out of it.
