I have just installed iOS 7 on my iPhone. Now all of the podcasts that I listen to on the way to work have disappeared. Apparently the only way to fix this situation is to download Apple's Podcast app. I uninstalled this app, when it first came out because it was a piece of crap. Now they are forcing me to use their piece of crap. I hope they fixed it, though I doubt it.
The new GUI graphics are mistake. They add no new information. You asking me to learn something new, but there is no return on my investment. Now I have a good reason to switch next time around.
I recommend selling your Apple stock. They have peaked.
