A Hong Kong based company, Brando has been found to be selling a hand-held cellphone jammer which could block GSM phones within a 10 meter zone from the user. The company says that it can ship the device worldwide, and warns users to notify people if the jammer is being used in a public place, subtly ignoring the fact that it would be illegal in most countries. The device would block all four GSM frequencies, 850 / 900 / 1800 / 1900 MHz.
The company says that it "deliver joys to worldwide" - although the person who suddenly cannot make a phone call may disagree with that sentiment.
Nonetheless, being small enough to fit inside a coat would make it a tempting purchase for people who travel on public transport and are tired of people who shout into their mobile phones. If only they could make a version which jams personal MP3 players until the user turns their headphone volume down.

The same retailer was also featured on cellular-news last year for selling a telescope for camera phones.
