I have recently upgraded my itouch software to find that APPLE has REMOVED the PODCAST REPEAT functionality. This feature was the single most important tool for learning pronounciation (especially while driving). If there is anyone else who has experienced this please join me in creating a post on APPLE'S SUPPORT page.
If you would like more information on a temporary fix, see the attached thread that users have created.
