I saw this posted over at CrackBerry and thought I would bring it over here. I've been using this app all morning long on my Storm and I'm very happy with it. It's not a battery killer like some of the other media streaming apps are. Also, they have a great selection of podcasts available, especially in the sports category.
It does support listening through Bluetooth devices, however I strongly suggest you go to your profiles and turn off all alerts before listening. If your alerts are on and you receive a message, etc.. it will start the podcast over.
