uploaded iOS7 and found several apps wouldn't open. Podcast was the first app I noted wasn't working, so I deleted it with the intent to redownload it...App store gave me a message that the app wasn't available at the moment. The app store continued to say that for a week while I traveled. When I got back home, I restored the 4S with my Mac-top and all but Podcast app function well...Podcast is still misbehaving, have yet to delete and attempt to re download...thoughts?

edit...found that opening the frozen app from within the app store without having deleted it was succesful...something new for me...whatever, as long as I regained access as I use my Podcast App extensively!
