Cell-Phone Location Awareness - Tower Signal Strength

Last semester, some people in Dano's Networked Expressions class brought up an interesting alternative to GPS. No, I don't mean Gumspots. Getting a location from cell-phone signal strength is common use in 911 emergences, but US phone carriers aren't making the technology available to developers. Heather mentioned Python's ability to glean signal strength on Symbian phones (Nokia series-60), but that still leaves the question of "where are the damn towers?" Perhaps someone should start a guerilla movement to find and geocode all the cell-towers in NYC.

Turns out those lucky Brits have it easy, as demonstrated by World Tracker. This is actually quite scary.
