I have searched and searched as well. FreeCaddie is what I use on my Vogue right now and it works pretty good and better than the rest I've found so far.
GolfLogix looks like they have a pretty damn cool one, but right now it is for the iPhone, and BB only. The WM version is "comming soon" according to their website.
Here's the site...

At the top where all the devices are list simply click the arrow to the right and you will see a TP, click on it and you see the "comming soon" for WM
Wish they would hurry UP!!! Let me know if you find anything else better out there as well
