If you dislike being handcuffed to iTunes to feed your podcast-lovin? ears, this solution's for you: RssPlayer invokes streaming audio from RSS feeds, so you can listen or download for offline use.
Sadly rewinding or fast forwarding isn't possible, and you can't use it to find feeds. On the plus side, RssPlayer does remember where you were in the audio when phone calls and interruptions pop up (which is my main gripe with Stitcher Radio).
Not sure if you need something like this? At the bargain basement price of ZERO, there's nothing to lose in trying it out. But act fast ? According to the App Store page, it's only free for today. Then it will be $4.99.
