The Palm Phone Jammer is a cell phone jammer than can effectively shut down GSM 850-, 900-, 1,800-, and 1,900-MHz cell phone calls in a 30 foot radius. Oh happy day! The unit costs a paltry $166, which is a steal. My old cell phone jammer looked a lot like me waving a gun and yelling obscenities, so this might not only jam calls, but lower my blood pressure. Two birds stoned at once. Although gun waving is fun. I doubt you're going to get anyone to shit their pants with this thing.
