A Jailbroken app, but still.
One of the best things you can do to your iOS device is to Jailbreak it. The variety of apps, which would normally not be allowed on the App Store, is truly incredible and allows a whole lot of features to be introduced just as easily as downloading an app from the store. Here’s one of them: Windows 8 UI skin.
The skin runs on-top of dreamboard and is surprisingly robust. It replicates Windows 8′s Metro UI quite well with the smooth flowing titles, icons and menus. It even has a ‘desktop’ shortcut which allows you to switch between the normal iOS UI and the skin.
Check out the video below for a demonstration. It costs $1.50.
