Make a call and jam everyone else's phone

We've seen them before, but possibly not quite as innocently dressed. Basically, the device prevents handsets from contacting their related towers, cutting off the signals and preventing anyone making a mobile phone call or cutting off a mobile phone in mid-flow, in your immediate vicinity.
