We still don't have a clear picture if the new Windows Phone 7 Series operating system (also known as "Metro") will actually be made available on any current hardware (the HTC HD2 is a possibility, but its standing changes day by day). But you might be able to at least make your phone look like it's got what it takes, thanks to some clever skinning. Everything's still in the early stages and is a little janky, but you get the idea.
