The Blackberry buzz

We’ve all heard it: that staccato buzz coming over a telephone speaker, even when it’s off, and we look to play a game of, Who Has the Blackberry? The other day at a big event, I heard it over the loudspeakers. I wondered whether this was engineered in; it would be smart if irritating advertising for the ‘berry. But I see it’s called the GSM mosquito and new standards are supposed to eliminate it.
