Ladies and gentlemen, please, no jamming in the theater
You've probably heard the phrase in a science fiction or war movie at some point: "We can't get through, our signal's being jammed." Well, jamming is real -- not just for the military, but for anyone with a few hundred bucks. Jamming cell phones is the hot issue right now. In countries like France, Japan and Israel it is legal to use a device to disrupt cell phone service. In the U.S. it's not, and it carries a hefty fine.
But there are jammers in use here; no one knows how many. And there are jamming fans -- they might call themselves a "silent" majority. One of them is Matt Pullin, a senior at DePauw University who tracks the issue on his website. (Jeff Horwich guest-hosts.)
