Shortly after Apple unveiled iOS 6 at WWDC 2012, they released the standalone Podcasts app into the App Store. Previously, podcasts were downloaded via the iTunes app and could be played back in either the Music or Video app, depending on whether they were audio or video podcasts. That split, along with with the lack of any ability to subscribe to podcasts, made it a less than ideal experience (which numerous third party apps tried to solve.) Now, with the dedicated Podcasts app, and with its iOS 6 and iPhone 5 updates, Apple is better is solving it themselves.
Note: This was originally supposed to be part of my iOS 6 review but due to size and time constraints, I'm posting it separately, an belatedly.
