Cool stuff. But don't even try the Java version on a Windows Mobile Phone: it just doesn't work. Or maybe it's me...
The Windows native version looks very cool though. Since I don't have a GPS, I used it with
Navizon, a virtual GPS using cellular and Wi-Fi triangulation, and it worked great: displayed my position on the map and displayed the traffic information in my area.
The maps were a little slow to display though: I know it's not my internet connection since the exact same map was loaded much faster on Internet Explorer.
