Smart phone

Wouldn’t it be cool if your cell phone knew where you were using the triangulation info from the cell towers? That’s way, any time you take a picture with the built in camera, it would automatically tag the image’s EXIF info with the Lat /Long co-ordinates and your photo apps at home could translate that into human readable format or automatically tag the pix. If digital cameras supported Blue-Tooth, then they too could pick up that same info from the phone without having to build in a GPS thingy to do the same job.
