I didn't speak about 'accuracy', I spoke about 'refining' the location, which is what I have read is being done....whatever 'refining' is (triangulation etc)....the ultimate purpose of such 'refining' is to provide accurate geotagging information.

Bear in mind that, mathematically, a GPRS triangulation can be used to further reduce the error in GPS locations - especially if only only 1 or two satellites are locked. I have no idea how accurate the N900 GPS hardware is on its own.
