ZoneTag - Flickr auto geocoding for cellphone pics

Find your photos by location
ZoneTag can automatically tag your photos with the location, based on the cell tower, [near] which they were taken. The location of the cell tower is not known until our user community updates the city, state, or zip code of their photos on Flickr. ZoneTag is then able to map the cell tower to the location.
