CNN and BBC feeds are the obvious favorites. Yahoo! Podcast seems to be selfish (as always) and wants me to subscribe to other podcasts only through its web interface. Maybe that's okay for the desktop, but on my Symbian that's a compromise I'm not willing to make.
The one heart breaker was VOA. While I've used its podcasts heavily in the past without any glitch, it just won't work on my mobile. I wonder why.
