Every once in a while comes a device from Japan that I would love to sneak into the country. Of course, there's a little question of legality here. Either way, you can't beat the CX 200 Portable Director II Cell Phone Jammer.

Easily fits in your pocket, the CX 200 can be used in two modes:

• complete jam - that jams everything around for about 70 seconds
• ending your own calls - great when you want to discreetly terminate a connection

One of these babies costs around US $70. If they make it legal here, you know who'll have the first one!
