Does anyone here have/use a cellphone jammer? I recently met a guy at a corner gas station who was playing with his and it was hilarious. As cars were stopped at the light, several people would be on their phones. When he turned on the jammer they all looked at their phones like wtf!?!? I can see a real good use for one of these but I think they are illegal (fcc) and also have to be ordered/shipped from China. Still tho I think I have a new toy on my Christmas list.
