That is possible but it would shorten your battery life quite a bit and make your phone warm even when you are not talking on it.  So its only used in extreme cases.

That is very old technology and I doubt anyone uses it anymore.

Quote:

An Australian electronics mag stated that digital exchanges have this feature built in and nothing needs to fitted to your phone as it is already a bug, like the infinity bug whether you are on the phone or not.




That is definitely not true.  When the phone is on hook there is 48 VDC on the line and no audio path.  The microphone is not connected until you pick up the phone.  This functionality is integral to the way that phones are wired and there is nothing the telco's switch can do about it.  Also it would be easy to detect if something like that was happening.

load of crap, cell phons can be intercepted with most police scanners




True, but 99.9% of the calls are encrypted using GSM or CDMA and have been since the late 90's.  So unless you have some mid-range crpytoanalysis gear too it will just sound like static.  It doesn't take a professional cryptographer to break it, but its not something that the average high school kid could pull off.  Most people do it with old test equipment from the cell phone companies.

In some rural areas analog cell phones are still in use - Many tri-band phones still have analog, and if you are on some remote mountain top somewhere you will often see an A on your LCD, indicating that your call will use normal FM and can be intercepted by scanners.

and it's legal to do so




They passed a law in the 90's that makes it illegal to listen to cell phone calls with a scanner after some high profile people had their calls taped by reporters.  The law also said that all new scanners have to be incapable of picking up the 800 mhz cell phone band. 

I used to listen to cell phone calls when I was a teenager.  In 1997 I picked up a call between two lesbians having phone sex...after about a half hour one of them was like "Ok I am here! and the other said Ok I see you outside..come on in!".  I never listened to another cell phone call afterwards because I knew there was no way I could ever top that.

My scanner was one of the models that can't pick up the cell phone band, but by tuning 21.1 Mhz above the signals I used a flaw in the receivers IF to pick them up anyway.  If you are in the middle of nowhere (no CDMA/GSM service), give it a try, tune from 894 - 916 Mhz and you'll hear calls.




  You are right.  I worked as an engineer at Qualcomm from 98~2002.  Unless the government got their way and put backdoor keys into the chipsets, CDMA signals will just appear as noise. And it isn't crackable by 50$ Radio Shack hardware, or even 1 million dollar hardware.  The NSA can do it (maybe) but fat ass deputy dawg inhaling donuts and drinking coffee down at the local station doesn't have the technology.

Just google "cdma gsm scanner".  You'll get plenty of hits.  There's no encryption on these things, just a complicated method of multiplexing the signals.

Both GSM and CDMA use encryption.  GSM uses the A5 cipher and CDMA uses spread spectrum with a secret spreading key.

Currently GSM is the easier one to crack.

So CDMA is a multiplexing method rather than encryption and GSM uses a 20+ year old scheme that can be cracked with the computing power of a pocket calculator.

There's not much security there.  I'm not saying that every white van you see is listening to your cell calls, but it certainly isn't that difficult.

I agree with everyone who said it's a bad idea. Because its a bad idea.

Number one reason people get busted...they confess or admit to committing a crime. Nine out of ten court cases that get a conviction, do so based on information someone volunteered or a confession. So be wise and keep your mouth shut.

The vast majority of communications are monitored for keywords by various programs and facilities. That being said smoking a joint and bragging about it isnt likely to bring anyone to the door but why take unnecessary risk? Why brag about committing a crime? Nothing good will come of it at all. Period.

Btw, with all standard tech police or other agencies do have technology that will infiltrate or otherwise break it. Ive seen their computer tech in action for cracking computers and passwords and its pretty awe inspiring. Do I think they are going around cracking people's communications. Probably not. But they do have the ability if someone gets tipped off about potential drug activities then they get a warrant for a wiretap potentially based on probable cause due to a tip.

As sad as it is, the ones most likely to stab in the back esp about drugs or crimes are the ones closest to you such as family or esp friends.
