Cell phone common sense

Cell phone service disabled in New York tunnels
Authorities fear terrorists could use devices to set off bombs

NEW YORK (AP) -- Cell phone service was disabled inside the four tunnels leading into Manhattan after the terrorist bombings in London, but Mayor Michael Bloomberg questioned Monday whether the move "makes the most sense."

Cell phones have been used to detonate explosives in Madrid and elsewhere.

Now the problem with this is how exactly cell phones were used to set off the bombs.

In the Madrid explosions, alarms in cells phones were set on vibration, which sent electric impulses to the copper detonators connected to the explosives, Spanish authorities said.

Turning off cell service isn't going to stop a phone from having an alarm set to vibrate.
