If you have a subscription to Hauntcast on iTunes, you already know the feed doesn't work. I had to submit the new feed and there is a new listing for Huantcast on iTunes Hauntcast - Download free podcast episodes by Hauncast on iTunes. . Please subscribe to the new listing (with the new artwork) to get the latest episode and all the past episodes.
Sorry for the inconvenience, but iTunes wouldn't just replace the old feed with the new.
