Does anybody know anything about built in 'GEO SENSORS', inside mobile phones, which log information about the units location, movement, and sounds, on databases kept by Network providers? Did you know that it is possible to not only track a mobile phone, and potentially eavesdrop conversations, but also it is possible to establish whether or not a person carrying a particular mobile phone, is walking, running, standing still, sitting down, falling down, laid down, etc...
