We already know that all Windows Phone devices will be at least getting the new Start Screen from Windows Phone 8, but what we don’t know is when. A new app in the Marketplace will allow you to expirience the new Start Screen without having to wait for that upgrade.
W Phone 8 is an app created by the same people who made Clearer and AppBuilder. With this free app you can play around with a WP8 Start Screen almost as if it’s the real deal. You get a set of tiles that you can rearrange, resize, and remove, but you can’t add any of your own. It’s a fun, easy way to try out WP8 while we wait for WP8.
