IOS – How to search more magazines in Apple Newsstand on iPod

In the iPhone app, at the bottom of the list of episodes you will always find the link you can tap to "Get More Episodes". That is a hardwired link to that podcast's page on iTunes. This link will be shown regardless of whether or not there are more episodes actually available.

The podcast pages in the iTunes app and in iTunes on the desktop are the same and contain the same episode list. The episode lists themeselves are not controlled or determined by Apple or iTunes, but by the makers of each podcast. Podcast makers use different feed systems (like adlib or feeedburner) and they have different bandwith limitations depending on their own usage terms.

Podcasts like This American Life, for example, in order to minimize bandwith costs, will only keep the latest episode on their episode list. So when you tap on "Get More Episodes" you will only get a list of one. Podcasts like This Week In Tech, for example, have bandwith sponsors that allow them to host most of their back catalogue. So when you tap on "Get More Epidodes", you will get a list of fifty or more. It basically all depends on how each podcast maker handles their feed and bandwith costs.

Hope this helps.

What you refer to as "iTunes mode" is actually a separate application called iTunes. The only way to get back is to relaunch the iPod app. If you have a multitasking-capable device, you can double tap on the home button and the iPod app will be there as it was the most recently used app.
