I don’t use Google Maps for Mobile often, but when I do it’s a godsend. It’s slow, though. Trying to pin down the current position takes most of the time – invariably I’ll type in road names / an area and after a 20 second delay it’ll come back with ‘location unknown’, or lots of possibilities, most in Scotland. It probably won’t be long before all phones have GPS built-in, but for now Google have launched ‘My Location‘, which uses phone-mast signals to trace you to a circle with roughly 1km radius. Mine is 1.7km, centred roughly on Stratford. I can then search the local map for a street name, and I’m sorted. It’s possible to search for local businesses too – this would have been handy a couple of weeks ago when I was trying to locate a particular restaurant in the centre of London.
