Updating my feed

Hi All-

I entered the "update feed" tag with my new feeds url into my existing feed that iTunes knows about, but it hasn't updated yet. It has been almost 24 hours. I validated the new feed using itunes "subscribe to feed" and it totally worked, but iTunes has not updated. any ideas?

old feed: http://www.switchpod.com/users/julenisse/feed.xml
new feed: http://julenisse.libsyn.com/rss
