OK, I go into the Podcast App and have been to every screen and checked every menu, but I can not find an option to "Add Channel" that will allow me to enter a URL of podcasts that I want to subscribe to.
The version of Podcast that comes in 6.0.0.141 is not the most current version of the application. The most current version is 1.0.0.36, so I DL'ed it off App World and rebooted.
Even after it came back up, there is still no option that I can find to Add A Channel.
After upgrading the application you have to go into the "Explore Podcasts" option where the program will then give you the "license agreement". Once you accept it, you can then go back to the main Podcast screen and then the option to Add Channel is available.
