This technology has been out there for years. I was using one back in 1989. We had loads of laughs on Saturdays listening in on cell phone conversations between husbands in the car and wives at home yelling at him for picking up the wrong thing...going to the wrong place, etc.
The device would report the cell tower in use, the serial number and cell number of the phone being connected to.
what brand ? got a link ?
thanks in advance
Then let it be FREEEE!!!! Just like health care!
