iOS 6/Podcasts app audio bug
This also happened in the Developer Previews on my iPhone 4 (I now have a 64GB 5)
Basically, whenever an incoming call is declined, even if the phone is set to MUTE (via toggle switch), after the call is fully declined the Podcast you were listening to last is resumed at the same volume you were listening to it. In my case, full volume since I listen to Podcasts on the way to work in my shirt pocket. A rude awakening in the office, for sure.
Not really a question, but wanted to see if anyone else had this issue and maybe bring about awareness.
iPhone 5, iOS 6, Everything is up-to-date
