The WRC app is built using Qt technologies which means it's very easy to migrate it across platforms. It's currently available for Series 40, Symbian, Windows Phone and MeeGo devices. The experience is virtually the same on every piece of hardware. It's fast, responsive and lightweight.
If you're looking for the app, you probably don't need to speed at 130km/h anywhere to get it, just saunter over to the Nokia Store on your S40, Symbian or MeeGo handset or just tap the Marketplace icon on your Windows Phone 7-powered Lumia device. It's not even 2012 yet and the races don't start until late January, but who knows what might happen by then...maybe your phone will get run over. Just download it and enjoy while you still can.
