I have just downloaded the iPhone 2.2 update. Now my iPhone can download podcasts directly, without having to sync with my PC.
My question is;

How can I manage my podcast downloads? If I download podcasts through my PC in iTunes, I can change all sorts of settings.
But using the iPhone direct download from the iTunes store, utilising my wifi network how do I manage my podcasts? There seems to be no settings in iTunes on my iPhone.
Also, can I now sync my music on my PC's iTunes wirelessly with my iPhone?
