We suppose it was inevitable. Ever since Apple opened the iOS flood gates to accessory developers, we've seen things as useful as a glucose meter to as crazy as a toy quadricopter. Somewhere in between lies the Cobra iRadar ($130). This high-performance laser and radar detector provides 360 degree monitoring and integrates with a free iRadar app that goes beyond simple detection to notify drivers of speed and redlight cameras, known speed traps, and dangerous intersections, or basically anything you'll want to avoid.
