If you've seen our shots of Samsung's Armani redo, the F480, you might have noticed it's running a new OS. The UI -- called TouchWiz -- is based off of the company's Croix interface (which apparently was rushed out to compete with the iPhone), and will be used on all of the upcoming finger-touch phones from the manufacturer. The cats over at Phone Scoop had a chance to go one-on-one with TouchWiz at Mobile World Congress, and they've put together a pretty informative video that shows off the UI doing its thing. The inclusion of a new widget system, expanded menu options, and overall speed bump make this OS a notable step up from Samsung's previous offering. Take a look at the video after the break to see the system getting all funky-fresh.
