New York, Nov 02: New York City is lobbing the latest volley in the war on cellphones and could be first in the nation to penalise anyone chatting during a movie, concert or Broadway show. With 135 million people using cell phones across the country, the device has been celebrated, denigrated and increasingly regulated. Up to now, the concern primarily was wheth-er cellphones are a dangerous distraction while driving. But New York City's proposed law shifts the debate over cellphones beyond the realm of public safety and into the arena of social etiquette.
