I've been playing around with a few off these applications and seem to like http://tribalshout.com the best.
Others make me download software to my phone and require me to stream the podcast over a slow data connection.
This one feels just like using my voicemail. I happen to use MyFaves on T-Mobile so I don't have to worry about my minutes. I've been playing with a very cool Helio Ocean but still find myself dialing their number 415-233-6900 to access content rather than using the built in browser. Debating on getting an iPhone but it doesn't sound like I will be able to sync up wireless to iTunes and thus get my podcasts in real time
I like the fact that Tribal Shout lets me create channels. They seem to be working on some different channels like politics. They also let you blog right from you phone by dialing a number and recording your own episode....then give you widgets to place on other sites like myspace.
Lots to play around with here but I want to see what others are using.
