I've been having a great deal of trouble lately with my iPhone properly identifying where I am accurately and quickly (usually takes me at least 2 min). This may be a bug in my particular phone, but I know many of my friends are having the same problem.
I propose that we assist the process of acquisition by creating a voice app that allows the user to speak into the phone and say a major landmark/street name or series of landmarks that they can see. For instance, if I can't see the street name i'm on, but I can see Arby's and Johnny Rockets I can say "Arby's and Johnny Rockets" (landmarks right next to me): this is a unique "fingerprint" of the area and by using a google maps search (knowing the city and state), the app can identify the latitude and longitude of this area and feed that to the GPS device as a starting point. The GPS can work from that point on

I think it's a good idea. You probably should have checked the site before you suggested it--this was even suggested as recently as Oct 22.

I shouldn't have been so quick to say that this was already suggested--you've come up with a new feature that nobody has mentioned up-to-now, the voice-based position-recognition.
But like I said in the comments on one of these others, I've never had a problem with the GPS not being able to find my position once the satelittes are locked.
I do know that voice-recognition that's used in customer service on telephones almost never works for me--the only word I say is "operator" to talk to a human. I hope your system would be better.
