Why is #5 not on iTunes? I can only see 1-4 from my iPhone. I can't use desktop at work to download and move the mp3 to the iPhone, so as a result I can't take it with me right now and I will probably forget about this later.
Episode #5 is on iTunes, but there may be a problem with the auto updating. If you manually update in iTunes it will download. We'll definitely look into the iTunes auto update issue, but it may just be that it takes a little while for iTunes to fully register an uploaded episode.
