As you lock and unlock your iPhone device, you'll start to see that while the audio is playing back correctly, the information regarding your Podcast Episode isn't displayed at all.

One tricky aspect of the lock screen is the current play time label. We have to make sure to update this right when we expect our application to go into the background.
