"Twist the wires from the battery together and connect them to the bare wiring on the microphone"

First, that provides a dead short to the battery in the remote. Secondly, the remote works with IR, not RF..
BUNK!! ;D

Yeah... complete crap, not to mention in the US if you get caught with anything capable of jamming radio waves... you are going to be at minimum fined heavily by the FCC... and in a post 9/11 society you are probably going to have a handful of 3-letter agencies talking to you and nosing around in every corner of your life

If you want to listen to cell phone calls get an old Radio shack portable scanner thats about five years old. I remember reading that if you programmed in the harmonic frequencies of the cellular company in to them because they were made so cheap that the would pick up the signals. The ones they have now a days won't let you do that.

The main issue i have with intercepting calls is that I don't want to hear what people are talking about. I want them to shut up and let me enjoy my steak and beer. if somebody would post plans for a jamming device i might consider making it.

As of 2 days ago most/all of the major cell phone companies have shut down any of the cell equipment that was able to be received with regular radios, both the $300 consumer scanner and $15,000 professional receiver. Analog is a thing of the past unless some small mom-pop company in the middle of nowhere is still running one.

The law that bans consumer grade receivers from working in the cell phone portion of the 800 Mhz band is now a moot point. Doubt they will take the law off the book since it will be easyer to modify a law to include something else than pass a new one.
