This gadget would probably end up causing more harm than good. The phone has a sensor that can detect motion; if the sensor is set off the phone will dial a pre-designated number and let you listen to the room for 30 seconds. I'm no engineer, but if the phone detects motion, then is there much of a purpose to listening in? Just hope that the robber stubs his toe and lets out a yelp or it will just be wasted cellphone minutes. Eighty bones, available now.
