Fancy Last.fm? Fancy Windows Mobile? Then you’d probably fancy the Last.fm Windows Mobile app currently in development, which happens to be called Last.fm Mobile. The Pocket Personal computer version includes scrobbling and experimental radio functionality, but the Smartphone version can only scrobble from Windows Media Player.

The app has a healthy backing of supporters at the Last.fm forum, which is where you can learn where to download and how to install Last.fm Mobile. You’ll need Windows Mobile 5 or 6 and the .NET Compact Framework 2.0, which should be included with Windows Mobile 6.

Last.fm offers tools for discovering new music, social networking, and, of course, listening to music. The addition of WM functionality only makes it that much more useful.
