Network Dashboard is a rather nice Windows Phone app that allows you to pin common network tasks to your Start Screen. Network Dashboard was recently updated to version 3.0 to support Windows Phone 8. With the update the developer has dropped the price to free and brings along a few new features for good measure.
The version 3.0 adds a tile for location services as well as status detection for Bluetooth and Airplane mode. You also have a new default Metro Live Tile style and an in-app purchase for additional tile styles.
