Layers in Google Maps Mobile

Official Google Mobile Blog: Layers of fun in Google Maps for mobile 3.2: "Just as the world itself can be viewed through many lenses, the latest version of Google Maps for mobile allows you to view many layers of information on your map at the same time. Layers make it easier and more useful to find and interact with geographic content, like public transit, traffic (with incidents!), local search results, Latitude friend locations, Wikipedia and more. You can also see your own My Maps content as a layer on Google Maps for mobile. And finally, multiple layers can be combined at the same time to give you a content-rich view of what's around you."
