SPB Mobile Shell is a very popular user interface replacement for Windows Mobile and while we wait for Windows Phone 7 to be officially released we can get a taste of the next-gen user interface using a Windows Phone 7 theme designed by MSkip @ XDA. The theme isn’t new but has been updated very frequently and looks amazing now!
Take a look at those screenshots to see what Windows Phone 7 v2 theme for SPB Mobile Shell looks like:
This theme is for SPB Mobile Shell 3.5.5 and comes with the following features (from XDA):
+ All new layout with invisible buttons at bottom of the Home Hub for Carousel (bottom left) and menu (bottom right).
+ Home Hub is scrollable so you can add as many panels as you wish or make up your own.
+ Static link on the Home Hub (opens the Shortcuts Hub) so no matter where you are in the Home Hub you can always see it.
+ Panels are mostly made up of shortcuts and custom shortcut skins so easy to change images or look (if desired).
+ New menu bars in mobile shell screens.
+ All Screens fully set up for LandScape mode.
+ Lots more that I cant think of right now. Find out for yourself
I recommend also to look at the changelog @ XDA, MSkip updates his theme frequently.
You can see an older release in action in the following video:

If you don’t have SPB Mobile Shell, you can get it @ http://www.spbsoftwarehouse.com/products/mobileshell/. While it is not free it definitely is worth a try as it comes packed with great features.
