Hard to say that I'm surprised. It's a well known fact that mobile providers can and are tracking mobile phone users. That's really easy to do because cell phones send signals to base stations to reveal their location to the network.
So that's not surprising that manufacturers of cell phones decided to start their own tracking.
R U kidding? cell phone jamming is dangerous! When I contacted the manufacturer of cell phone jammers http://www.jammer-store.com/ I was told that all types of jammers block absolutely all phone calls so you won't be able to call 911 when you need this. And that damn risky if you ask me.
