Finding Location Using Cell Phone Tower ID?

[Woodtroll]

Hello, folks,

Not really "gadgets or gear" but a lot of computer questions end up here, so I thought I would try...

Is there any website or program where I can punch in values from a cell phone reading (Tower ID, MCC, MNC, LAC) and get lat/long readings, or even access to a map of the location?

I know there are applications that will show the user of the cellphone where they are, but that is not what I am after.

Thanks!
