I had an HTC Wizard that ran on Windows Phone 5.0. It really was a piece of shit, but I loved the slide out keyboard and the fact that I could stream internet radio with it (when I was on wifi).

But I remember having to explain to someone that no, just because it ran ‘Windows’ it couldn’t run Limewire. That said, it’s entirely possible that someone wrote a version of Limewire that it could run.
