Google Maps on Windows Mobile(tm) devices

Those of you with Windows Mobile(tm) devices can now search for local
businesses and get real-time traffic reports using Google Maps. This
edition also includes some custom features: contacts integration, GPS
support, draggable maps, and tap and hold menus. And since Google Maps
for mobile is available on more than 300 phone models, chances are
good everyone can download the application and always know where they
are when they're on the go.
