GPS technology

Of course, I am not anti-technology and am in awe of the iPhone just like the next gadget freak.  It is not inconceivable that the madmen tinkering with electronics have blinders on to the side-effects of some technology, some experiment, or would deliberately do something stupid.  And even though satellite-based tracking technology exists, even fewer people are likely to consent to having their whereabouts tracked on a daily basis in the off chance that they might get lost on a backcountry road for a reverse lookup phone number.  New phones using GPS technology allow parents to track the location of a phone and thus, hopefully, their child.
