Cell phone rants are passe... Now cell phone vigilantes are all the rage (and no, I don't mean people throwing phones at purse snatchers). These are people who stop whining about rude cell phoners on trains, planes, and theaters (among other places) and actually do something about it... Don't get mad, jam their phone signals. It's now as easy to snag a wireless jammer as a bottle of fake V!agra online, and also just as illegal. Still, there's a certain poetic justice to watching a loud cell phone yapper scream, "HELLO!?!" into a useless phone for 30 seconds. Mind you, the technology is not new, but the FCC isn't a fan of people running around jamming wireless signals. So, you can't just head to the local Radio Shack and pick one up. Still, it sounds awfully fun. We'll talk with WIRED's Ryan Singel about the technology.
