I see. Have you tried Podcaster recently, though? They have made a lot of improvements to it, and I know it is recognized as an audio app by the iPhone more than it used to be. It might be worth a try, especially if you already bought it previously.
In any case, some of the iCloud syncing may not work right away, and some of it may depend on Lion as well, so even if some of these features aren't showing up right now, that doesn't mean they won't later.
