Well this is one of those use-at-your-own-risk sort of devices. The Yapper Zapper is a cell phone jammer that blocks GSM, CDMA, DCS, PHS and 3G signals up to 10 meters (30 feet). It works continuously on a single charge for up to 2 hours and is about the size of a chunky cell phone itself. Put it in your pocket during a movie screening and… well, you get what this does. Or a commute to work. Or a meal. The places where something like this would be a godsend are almost endless.
Sadly a device like this is illegal in most jurisdictions we can think of, while incessant yammering in inappropriate places is not. We’re not even certain you’d be able to get this shipped to you. But it will cost you $109 to try.
