The new Metro UI is the newest part of the Windows Mobile UI family, and with the new Throttle Launcher being released. The theme gives Metro a chance to shine in our WM6.X devices. The new version of throttle launcher that was just recently released already has a WP7S phone theme going for it. The theme was done by an XDA member that is yet to be released.
I am currently standing by to play with the theme on my Touch Pro2, because I am getting bored of the same old. I am ready for a new look on my phone, and since I am going to still buy WP7S, I will have a lot of the same for a long time.
The theme looks very nice, and if you have been itching for the new Metro UI, this might be something you can give a try.
Play with Throttle Launcher, and get progress on the new theme.
