Yeah - it appears that iTunes is behind on updating the FTL listings via the iTunes store, which is a nuisance for those of us who like to stream on an iPhone. I emailed Ian and Mark because I was having the same problem and their tech guy emailed me back -- they're aware and are working on it.
iTunes blows sometimes. In my experience as a podcaster, I've found it very hard to control what shows up when as far as a podcast. When you update a podcast, sometimes iTunes picks it up quickly, sometimes slowly, sometimes not at all, and if you search online for a solution, you see that all sorts of podcasters, big and small, have had this problem for years and iTunes isn't terribly responsive.
So this week I've been listening right off the front page,
http://www.freetalklive.com/. You can download or stream off of there using their quick link to the last show, on PC or iPhone.
I'm also going to experiment with a different podcast client like RSS Radio since iTunes is so unreliable.
