If you like to listen to podcasts, but are dismayed at the way they are relegated to their own Podcasts app in iOS 6 (and in iOS 5 as well), you don’t have to use the Podcasts app. What’s changed in iOS 6 is that podcasts no longer show up in the Music app; with iOS 5, they still did, and you had the option of using either app. Now, you no longer have that choice, assuming that you have the Podcasts app on your iOS device.
If you recall, you had to install it on its own; it’s not part of iOS. So if you’d rather continue to listen to podcasts in the Music app, just delete the Podcasts app. When you open the Music app, tap on Other and you’ll see a Podcasts entry. You can access your podcasts from there as you did before.
