If you subscribe to a number of podcasts, it can be quite a task removing old podcasts from your iPod or iPhone and adding the new ones. You can automate the task by using a simple iTunes Smart Playlist.
To automatically sync podcasts you haven't listened too, create a podcast Smart Playlist:
- In iTunes, select "New Smart Playlist..." from the File menu
- Specify these settings:
- "Match ALL of the following rules"
- Genre contains Podcast
- Play Count is 0
- Check "Live Updating"
- The Smart Playlist you've created will list all unplayed podcasts
Sync this Smart Playlist to your phone and you'll automatically have unplayed podcasts synced to your iPod or iPhone every time your sync.
