For a mere $60 these people will sell you a phone case that will block all signals from reaching the phone. Including incoming calls and texts.
Ah! Good old-fashioned paranoia. The project page is full of paranoia inducing half-truths and nonsense about both the Government and sinister hackers being able to trace your phone, listen in on your calls, and activate your camera without your knowledge.
“Now with friends-locating-software like Google, Facebook, Twitter, and Foursquare, the problem is getting worse.”
Hey, dumb-ass, those things only use your location when you make a post. Putting my phone in an internet-blocking case while I’m not using it doesn’t stop me from tagging my location on Facebook.
Too bad phones don’t have a built-in way for a user to go “off the grid” for their own privacy. Oh wait! They do.
You know that great thing about airplane mode? It saves battery power. This case will drain your batteries as the phone cranks up the power to its transmitter in a futile attempt to stay connected to the phone network.
These people selling this case are snake-oil salesmen of the worst sort. They scare you into buying a product you don’t need, and convince you that it solves problems you should legitimately be worried about, when it really doesn’t. (Geo-tagging on social media, malicious apps, and tracking software placed on phones by a relative are all serious issues not solved by this case, but their project page implies otherwise.)
