We've been keeping you up to date on the developments surrounding third-party iOS apps and the Apple TV. Steven Troughton-Smith has been working with other developers to bring all kinds of iOS apps to the jailbroken Apple TV with the hopes that Apple will open up access to the App Store for its set-top box.
The first app to be shown publicly for his project is Jackoplane's Frequencies. As you can see, the app is running fullscreen on the Apple TV in the full 720p resolution.
