One of my favorite (missing) features of Google Maps on my N95 was the ability for it to pick up my (approximate) location based on which cell tower I was connected to. I'm talking you fired up Google Maps, pressed 0 and within <5 seconds it took you to your location (which is faster than it even takes Ovi Maps to load!).

It was INCREDIBLY useful for being able to do quick location based services. Quite possibly the #1 feature I am missing on the N900.

So my questions are, was that something that Google built into Google Maps, something like a database of cell towers, their GPS coords and coverage radius? What level of effort would be required to have that same quick/approximate location information be made from within the N900?

My next question is how should this be worded into a Brainstorm? I want to give as much accurate technical details as possible so its not vague what is being requested. Also, this doesn't necessarily have to be just for Ovi Maps, I would think other programs could find this capability useful.

What I am wanting is a near instant approximation based on cell tower while the GPS is still attempting to get a more accurate location in the background.
