BeyondPod is FREE, Open Source, RSS feed reader and podcast manager (podcatcher) for Microsoft Smartphone and Pocket PC.
Smartphone Thoughts has the article here.
Got it, now I can stop wasting hard drive space using itunes as a podcatcher.
I'm still going to use NewsGator as my RSS reader.
EDIT: after 2 weeks, I'm loving it. Got all the TWiT feeds in there, and all of Leo's goodness on my phone!
