Cobra is a company long-known for making radar detectors. Now they are offering the iRadar system, which combines a Cobra detector unit with an app for iPhone and iPod touch. The detector unit provides 360-degree protection from all radar and laser guns, and a city/highway mode prevents false alerts. The iRadar app for iOS devices uses visual and audible alerts to notify you of speed and redlight-camera alerts, known speed traps, and dangerous intersections. You can see a history of alerts on the map view, and you can control the detector functions from the iPhone/iPod touch. The Cobra iRadar is $129.99.
