There's one potential issue with this in that all electronic devices these days can store data. It may not be able to transmit while in the pouch, but there's no reason it could store and forward when you next come into rage of a wifi station. We already know malware exists for mobile devices; there's no reason a 0-day exploit can't be implanted to do just that. Besides, it's not just your phone that could be transmi…

Store and forward what? The only thing I'd want to prevent my phone from beaming to the mothership is my location. If your phone is inside this Faraday shield then it can't get a GPS location to store. Edit: microphone will still work inside pouch

Why wouldn't the microphone pick anything up? Sound waves are unaffected by a Faraday cage.

Store and forward any audio it picks up. Why stick to GPS when your location can be triangulated by cross referencing the sounds around you? E.G. A fire engine/ambulance, school bus with loud children or garbage truck passing by at a particular time or the voice of someone else who's cell isn't protected and is being monitored.

Software to accomplish these things already exist.

If the pouch doesn't work as intended and the phone still has a very weak connection to the tower, the phone will transmit at maximum power, which will just eat through the battery life when sending and receiving data. I can't see this becoming successful if the pouch has this issue.

Confirmed. I work next to a Faraday cage and I get almost no signal - none when I need it - and battery life sucks. At weekends I get plenty of life despite using the phone more.

Um, what is the use of a shield that blocks signals from going to your cellphone? What is the value of a cellphone inside such a shield? You can never take it out of the shield, and you can never use it.

> You can never take it out of the shield Why would you arrive at such an absurd conclusion? The pouch provides control of when you are tracked.

As someone else pointed out, there's no reason it can't track and store things for later, when it does have a connection.

Starting with the before and after GPS positions, one could estimate likely connecting paths using accelerometer and microphone inputs.

If you're going to keep your phone in a Faraday cage pouch, why not simply turn it off?

Because turning it off doesn't work. You can't fully turn it off without popping the battery out.

I recall seeing some work on fingerprinting phones that are off by the differences in passive radio signatures of their communication circuits.

So we pay $400+ for these devices every couple of years. But we don't trust the manufacturers nor the carriers. Some are paranoid that they're tracking every detail and transmitting at every opportunity.

Yet we continue to buy them?

Seeing the picture of the phone in the case, I can't help but think that this is a rather ridiculous state of affairs. If we don't like being tracked, if we don't trust them and if they breach our privacy, why don't we stop using/buying them?
