You can try FeederReader. FeederReader is software you install on your Pocket PC. It can download podcasts and rss feeds directly to your Pocket PC using any internet connection, including Activesync "Internet Passthrough". I recommend using Activesync 4.2 or above for this purpose regardless of the OS you use on your Pocket PC.
If you need help with this, just ask over at the FeederReader Forums (
www.FeederReader.com sidebar "Forums").
