As you'll have noted from the recent post about the new features in the released Nokia Maps 2.0, cell-id-based location has been added to the existing GPS support. Andrew over at London Calling has a definitive set of musings as to where this has come from and on how big a deal it will be to keep this extra ID database up to date.
Read on in the full article.
Now Nokia Maps becomes useful for non-GPS based Nokia phones. Pretty sweet. It also allows to do 'location' based search while indoors. Pity LocationTagger is on its last release and is not going to implement it. It would be nice to be able to tag photo's indoor. It is a very smart move from Nokia. Cell based location data could be used to filter out GPS-errors and enhance GPS accurracy.
Question: I have N82 on AT&T in the US (Washington DC). "My Position" does not seem to work at all. 😞 Like right now its showing the dot on top of our house, while I am 4 miles south at my office. What gives? Any ideas?
Clarification: I mean the network based estimation of location, not GPS.

In case of no cell-id info or gps-lock the 'my position' symbol stays at the last location you had a position fix. For the cell-id info to work you have it enabled in the correct preferences menu where also AGPS enabling is found. Make sure for the methods for positioning 'network based' is flagged.
Accuracy is generally on the worst side of a mile though with signal dampening by indoors it could well be more depending on the frequency the network is. Another possibility is that the location of your cell-id at the office is unknown.

How does this help GPS when cell based is so inaccurate?
