Gearing up for the eventual release of iOS 6, Apple has released earlier today a standalone app for discovering, subscribing, and playing podcasts on your iDevice. Simply called Podcasts, the universal app will help streamline the entire podcast experience on your iPhone and iPad. Currently on iOS 5, you you can stream and listen to podcasts right from the iTunes.app, but if any were downloaded for offline listening, you’d have to make your way to the Music.app to access those files. Now with Podcasts, everything is done under one roof. An all-new “innovative” new Top Stations feature lets users find and try new podcasts from a variety of categories, including arts, business, comedy and more.
