In line with your reply, what I'm getting at is, does anyone know the approximate density of towers in central London/central Oxford?

How dense is "high density"? Only anecdotally, but when I tried this in central London last September(?) on my n73 it was reporting ~500m accuracy. About 15 miles outside of the centre in a reasonably built up suburban area I get ~1700m accuracy, whilst in central Oxford its about ~1000m. None of which are particularly useful for any real world applications as far as I can see. Not had a problem with it locking up on an n73, either using cell- tower or bt gps for positioning. Wonder if the n95 issue is something to do with the built in a-gps?
