Color ‘hack’ allows users to spy on anyone from anywhere

So, I'm confused about this one. Actually, I read about this somewhere else a few days earlier, and its been bugging me since... Wasn't the big thing about Color that they didn't use GPS to pinpoint you? They had some cool tech (that apparently justified $41M) that located you using bluetooth, audio input, lighting, etc, etc and Bill Nguyen basically flat out said GPS sucks and they don't use it.

So... Why does this hack work? Apparently they are still using/collecting GPS data? Anyone have a better idea than I do on this?

How is that a vulnerability when pictures are public inthe first place anyway? (the geolocation filter is a mere convenience)

Just wait until this is used to put in picture ads or more subtle product placements everywhere ...

just imagine using this hack in foursquare...
