I've been listening to The Apple Phone Show since before the iPhone launched. I think this is the one podcast that I'd recommend to all iPhone owners.

The Apple Phone Show provides a good balance of features, news, and discussion about the iPhone in a concise format. Host Scott Bourne and his regular guests (most frequently Andy Ihnako and Chris Breen) cover all of the important developments in the market each week with a minimum of rambling. (This seems to be a particular problem for some of the other popular, technology-oriented podcasts).

This show could easily make the jump to syndicated terrestrial radio or satellite radio, if the right channel for it existed.
