Compass app shows the way

Vito Technology Inc. today announces GyroCompass 3D 1.0 for iPhone 4 and 4th generation iPod touch. Gyrocompass 3D is a software compass built on gyro, camera, and accurate celestial maps.

To use, point the built-in iPod camera towards any sky object, like the sun or moon and swipe the app-generated sky to match the real one, and voila... a fully functioning software compass.
