I yes, I missed your GGP. But it still doesn't work. If you actively use a hotspot then IP GEO tracks you. If you use wireless data then you can be tracked by cell tower triangulation by the network operator, by GPS, and also by passive wifi tracking that we've been discussing.

I suppose that you might be able to try tunneling all of your outbound data through a VPN tunnel, but at that point you might as well go back to using internet cafes and phone booths.

I prefer misdirection. Set up a device that will appear to be 'you' in many places at once. For instance, google and facebook both routinely believe that I commute from New York to London at least 15 times a day.
