After I got my ipod touch yesterday, I became completely perplexed by how it could geolocate it's current position without any GPS or cell phone circuitry.

(No one I talked to all day seemed to share my curiosity on this.)

Then today, I got fed up with solving this riddle and just looked it up.

Looks like the heart of it is a massive, self-healing, wardriven database.

Accordingly, the time-to-first-fix is phenomenally faster than GPS. It also thrives indoors in well-populated areas where GPS might be unusable.
