Google Maps is the best BlackBerry mapping solution I’ve found and it just got a whole lot cooler. The Layers function will overlay different information sets on the the current map few. For instance, you can overlay a location-aware Wikipedia screen. Or Latitude. Or even make your own favorite locations and travel itinerary in a function called My Maps. You really should watch the demo video to see it in action. It’s killer. Update your BlackBerry at m.google.com/maps.
