After a long long wait Apple finally approved RaceBunny 1.0 for the app store. RaceBunny will let you send and receive tracks to and from your iPhone.
RaceBunny uses the new iPhone 3.0 build in maps and can record tracks. You can even send route courses to RaceBunny from within TrailRunner and follow the carrot symbol as it moves before your nose. Before you send a route course to RaceBunny, you can set a target speed.

Other than that, RaceBunny does not do much and but is free. Currently RaceBunny is the only application you can use to send GPS courses to your iPhone and follow them. So it might be an interesting use case to study for all other developers with great GPS solutions for the iPhone (hint, hint)

RaceBunny works best with the iPhone 3G and requires TrailRunner 2.1
To exchange data between TrailRunner and RaceBunny a domestic WiFi connection is being required.
RaceBunny uses the Build in iPhone OS 3.0 Maps requiring an internet connection to update the background map.

To use RaceBunny, follow these steps in a recent build of TrailRunner 2.1:
Go to Preferences > Synchronize and set RaceBunny as the iPhone partner application.
In the main document window, press the iPhone icon and select the send tab in the left pane. Start RaceBunny on the iPhone and press the send button in TrailRunner. The selected route should now be available in the list of routes within RaceBunny.
To receive tracks from RaceBunny, switch the iPhone tab in TrailRunner to Import.
Send a selected route in RaceBunny and TrailRunner should display it.
