iPhone - Podcast?

When a podcast is downloaded, where on the IPhone is it downloaded to. Thx.

There’s no traditional directory structure on the iPhone.
The “Podcasts” app has its own database, and that’s where a downloaded podcast gets stored.

There absolutely is, and the file will get saved somewhere under /private/var/mobile/Media/Podcasts.

It’s true that you are not supposed to be able to access it directly from a different, sandboxed application without any hacking. That is not because they used some sort of non-traditional non-directory structure for storage, however.
