Before you take your phone to incriminating locations stick it inside a metal box.

If you don\'t want to be tracked, just take the battery out.

This is a little over the top. What real benefit is it to know within 1000 yards where I am. Cell tower triangulation accuracy is highly dependent upon the tower density and placement geometry. Urban accuracy can be good

Yes, but what if the person you want to track has a more secure phone like a Blackberry? What then?

Every phone is tracked, no matter who made it or who\'s operating system is on it. The problem is how the networks themselves function, they have to know where your phone is physically located in order to send it a call; that\'s how the system was designed.
Besides just locating you though GPS for as little as $50 anyone can have complete access to your entire cellular phone, email, text messages, live calls or the ability to turn the microphone or camera on remotely to monitor your conversation and activities in real time. Experts have shown that there is almost no way to tell your phone is comprimised, and turning your phone \"off\" provides no protection.
National news reports give examples of domestic violence cases where compromised cell phones have resulted in women and children loosing their lives. Meanwhile congressional investigations have shown that device manufacturers have been installing tracking software on products like the I-phone and android family of products before they leave the factory. New technologies like Google Wallet create an additional level of exposure as cell phones handle banking and financial transactions.
We set out years ago to solve this problem and the users of our \"Privacy Case\" feel safe and secure knowing that no one will be able to track, eavesdrop or monitor private and personal conversations through their cell phones and wireless devices.

Dear Mr Snake-Oil (err - \"ThePrivacyCase\"). Electronics don\'t work without power, so unless you\'ve written private info onto your phone\'s case with a marker pen, then yeah, turning it off is going to protect you.
As for your silly cases - get real. If the phone can recieve a call, then the case does nothing. If the case blocks calls, then the owner may as well turn their phone off and save battery at the same time. Sheesh...
GSM towers need to know the approximate distance of your phone from the tower, because they need to advance or retard the instant they they transmite GSM data packets out to you (as does your phone back to them), such that everything is neatly syncronized to the speed of light. In other words, if your phone sent a datapacket at the exact same intant that someone next to you did - those packets would collide. If you were 2km from the tower, and that other person was 1km from the tower, you have the exact same problem, except with the slightly different timing issue now, because the \"exact same instant\" is now 1km of the speed of light apart. You get the idea. That\'s why these things are call \"cell\" phones.
These guys track people because the cell tower talks to the phone when they instruct it (by placing a call), and they \"sniff\" the GSM call transmission negotiation stage in order to extract the speed-of-light syncronization data from the call. It\'s an 8bit number. If you\'ve got an old nokia, you can put it into service mode, and you can see these numbers on your screen. If you know where the tower is, you can thus figure out roughly where the call recipient is.

Chris, you apparently have some idea as to how cell phones work, but you are obviously not aware of the spyware and tracking software available to consumer, corporate, and government clients. I did include numerous news reports on our blog of how these things programs work, including explanations in multiple reports that these programs can be installed without ever touching your phone. It is also explained clearly that the only thing needed to do this is your phone number and once installed they can used to turn your phone \"on\" even though you have turned it \"off\". I also included numerous stories highlighting the loss of innocent life that has resulted from the exposures these devices create.
If you refuse to take the time to watch and learn the information we provided for you I encourage you to Google: Cellphone Spyware

Hey Chris, one more thing to point out from the "snake oil salesman", something I actually just noticed. Gizmag already covered EVERYTHING I said in 2007... Look at the bottom of the related articles list below. The article is titled "spying via mobile phone". The first line is and I quote "A new software technology available only to law enforcement officers allows officers to listen to room conversations even when a phone is switched off." and that was in 2007 before a whole mess of companies began to make spyware available to the consumer for your cellphone that can do the very same thing.
Not really trying to bash you because when we started out, we didn't realize just how bad the problem was either.
The difference was we were willing to admit we didn't know everything and set out to find out what was possible and what wasn't and now the users of our "Privacy Case" feel safe and secure knowing that no one will be able to track, eavesdrop or monitor private and personal conversations through their cell phones and wireless devices.

I am going back to carrying my old analog phone. It is still good for 911.
