Over on the MRKTNGman S60 blog Jouni gives some details of a forthcoming Nokia Podcasting Appliction for S60 3rd Edition. The program allows you to update podcasts on a manual, automatic or scheduled basis over a WLAN or 3G connection. The application will available in July and will be S60 3rd Edition only.
The program includes the ability to search for podcasts using various directories (results are returned as OPML files).
The program is independent of any one directory of podcast list and it looks like Videocasting (via MP4 files) will also be supported.
The program is integrated into the phone so you can send podcast and podcast links over MMS or Bluetooth.
