Yep, it is pretty cool how they do that with cell tower triangulation. By the way, "triangulation" is exactly how GPS works too, just with a WHOLE lot more accuracy, since the signals and data from the satellites were designed for such purposes.
Free is free, no doubt - but I'd strongly recommend to everyone to take the 30 day free trial of full TeleNav. $10 a month is really inexpensive, in my book, and it is so useful that over 90% of those who try it end up subscribing. Here's a great example of how its indispensable to me - at night, when I'm coming up on a turn from a major, busy street to a specific side street, it sure is nice to watch the thing count down from .5 miles to .2 miles to .1 miles to 493 ft to 247 ft to 29 ft as I approach the correct side street. No more trying to slow down on a busy street with lots of traffic in an attempt to read street signs because you know you have to turn on ONE of these several side streets, but have no real idea which one until you can read the street sign. As nifty and technically cool as the cell-tower triangulation is, its not going to get you that.
