According to screenshots posted by the German Blog Schimanke.com, Apple will indeed be adding over-the-air podcast downloading in the next iPhone update. Shedding more light the feature's implementation, the screenshots show that Apple will be including the iTunes podcast directory in the iTunes mobile app. The directory will be available over cellular and Wi-Fi networks and both audio and video podcasts will be available. Podcast downloads will be limited to 10MB over the cellular network.
