A 3cm by 3cm display marked as an Apple component is causing some excitement on the internet.

The web site tw.apple.pro, perviously responsible for accurate discoveries of components for the iPhone 4, claims to have received this component from a reliable source. And the Apple branding on the part suggests that at least it is an Apple prototype part.

Guesses so far for what this component could be for range from an iRemote with a touch display for the rumored new AppleTV, an iWatch, or a revised iPod Shuffle “Touch” with a display.

9TO5Mac have a great little concept sketch from one of their readers.
