For the past week I've been tracking my girlfriend through her mobile phone. I can see exactly where she is, at any time of day or night, within 150 yards, as long as her phone is on. It has been very interesting to find out about her day. Now I'm going to tell you how I did it.

First, though, I ought to point out, that my girlfriend is a journalist, that I had her permission ("in principle ...") and that this was all in the name of science, bagging a Pulitzer and paying the school fees. You have nothing to worry about, or at least not from me.
