Submission + - Google to release free GPS app for android. (blogspot.com)
Today we're excited to announce the next step for Google Maps for mobile: Google Maps Navigation (Beta) for Android 2.0 devices.
This new feature comes with everything you'd expect to find in a GPS navigation system, like 3D views, turn-by-turn voice guidance and automatic rerouting. But unlike most navigation systems, Google Maps Navigation was built from the ground up to take advantage of your phone's Internet connection."
