So this past week's episode of Numb3rs seemed to be designed specifically to refute my previous log entry where I said GPS is not part of cell phones.
It seems I was wrong. I am sorry Numb3rs for my misunderstanding.
According to the show, it seems that when the decided that for emergency purposes, that cell phones should be trackable, the didn't use triangulation from cell towers. The actually put a tiny GPS chip inside all modern cell phones.
Wow.
So I guess they were right when they said they used GPS with the phone. Of course, in the episode, the person was in a library. Inside buildings is a very poor place for GPS reception, so I still have some doubts.
Then a very short while later it hit me. There is a GPS inside most everyone cell phone. And they don't let you use it! It would be so simple to show locations and do some simple coordinates on a cell phone. The data is already there. It would only take a simple program! Man - think of all the people who could be geocaching!!
