-------Original Message------- From: Madhu Menon <webguru at vsnl.net> How 'bout a portable one that fits in the pocket and can be used to disable mobile phones of people who talk too loudly, especially in restaurants and movie theatres? ------------------------------ Been around for some time, but quite illegal, last I heard. Pretty sure I saw one in action once in a mall - saw 4 people suddenly slapping their phones simultaneously in about a 20 foot grouping. http://www.google.com/search?q=cell+phone+jammer Chris
