Is this the end of cell phone rage? Pocket size cell phone  jammers that block signal of inconsiderate callers set to be the next big thing

Most commuters have experienced rage at having to listen to fellow passengers' phone calls.

But anti-social travellers are increasingly taking matters into their own hands by shutting down fellow commuters' conversations with portable cell phone jammers.

Jennifer Lopez demonstrated one in the film Enough. But the worrying new real-life trend came to the forefront this week when one Philadelphia bus passenger was caught by baffled fellow commuters.

'I guess I’m taking the law into my own hands,'he told a reporter from NBC10, 'and quite frankly, I’m proud of it.'

The jammer was busted by a co-traveller who noticed that everyone on the bus on his/her cell was having trouble getting a signal.

The jammer was holding a device hat looks like a walkie talkie with four antennae in his hand.

The commuter explained: 'Anytime someone would try their cell again, this guy would subtly turn in their direction, press a button and point it at them, then continue reading his book under his creepy hood'

Devices, cost from $40 to more than $10,000 on websites like

Users feel they are gaining some control against what they see as an increasingly inconsiderate society.'
