I have gone thru all the obvious methods of deleting played podcasts from my iPhone to no avail. I have iTunes set to "keep all unplayed episodes" and that works just fine in iTunes, but in my iPhone it just keeps adding podcasts and won't eliminate the already played ones. Some podcasts can be an hour or two long and after you get several of these on the phone, well it takes up space unnecessarily. The only way I have found to get rid of unwanted podcasts is to go into my iTunes folder on my laptop and delete the "podcasts" folder of all its wares. There must be a simpler solution to this problem, yes?
