Someone over at RIM has recently leaked an exciting WM application. The Blackberry Application Suite which is used to load the Blackberry OS on to WM phones. There have been rumors floating around for a good while that RIM was working on something to take over WM devices. Well finally it's been leaked for you WM users to play with and realize what you're missing.
It has been successfully installed on the TAEL ROM Standard WM 6.5.1 OS. It isn't an OS replacement, just an application suite that will allow you to run the Blackberry OS on top of you're WM device, this way your WM phone can at least have something on it worth value. Word is though you have to be on a BES network to get it to work.
I think it's great to see RIM finally starting to move outward and expand on other devices aside from the ones they produce. Granted this will slow down development for Blackberry addicts devices, hopefully RIM will get enough man power to be able to juggle both seamlessly. Anyhow, here is the download link:
