I wasn't talking about communications being intercepted, I'm primarily concerned with tracking. It's hard to get by in life without a cell phone in this day and age, and it would be nice if there was some kind of tweak or mod you could do to your phone to stop it from being used as a tracking device to monitor one's movements and location at all times. I get leaving it at home if your on the run, but us privacy buffs need a safe way to carry a mobile phone and not have to worry about big brother keeping tabs on where we sleep/eat/etc.
