Thanks for the clarification. I suspect that my G1 has a bad GPS module because I find that when I have it disabled, I can get a somewhat accurate measurement of my current location via cell towers or whatever, however if I have it enabled, it can't figure out where I am at all (at least not within the amount of time that I am willing to wait for it-- 1 minute or so). So I leave it disabled pretty much all the time in an attempt to keep the battery life long. If it were up to me (and I must admit I have not looked at how the location API works), I would have location services return an imprecise value quickly (via cell towers or wifi or whatever) and refine it as the GPS came online. Sensor fusion is still an active research topic, but there are at least some simple heuristics that could be used if it was inefficient to make a full Bayesian inference.

I seemed to have a similar problem a few months ago. I think there is also confusion as to the "location" settings -- there doesn't seem to be one setting that turns off all location querying ability, so you can have "use wireless networks" on, and "enable GPS satellites" off, and it still works, but the application calls it GPS (and the icon looks like a satellite). I think it cleared up for me when I turned on both location settings (use wireless networks and enable GPS satellites). I have not noticed a significant drain on the battery due to having both on, but I rarely use location based apps anyway.
