All Things D is reporting a rumor that Apple may be planning to give Podcasts their own app in iOS 6, to separate it from the iTunes app. This rumor is because users of the iOS 6 beta say that they cannot access Podcasts from the iOS 6 Music App.
Keep in mind that this particular build of iOS 6 is not final.
Also Audiobooks are missing from the iTunes app as well. Could this mean that Audiobooks will get their own app as well?
