Nokia's web-based Maps 3D client has grown exponentially more useful today with the introduction of new search, directions, and social sharing options. You can now explore any of 25 cities around the world by items of interest, check out reviews of local businesses where available, and obtain walking or driving directions to any destination within the city limits. Routes can then be shared on Facebook, Twitter, or via the conveniently provided shortened URL, and the same can also be done with any locations on the map. The whole experience is accompanied by grand, sweeping animations that zoom you in and out of locations. Maps 3D was always a very pretty exhibition of the world's most popular cities, but now that it's added legitimate utility to its arsenal, we're only left to wonder when we'll see it as a native app on our Windows Phones.
