Hey guys, I have been looking for a way to download podcast onto my iPhone using my iPhone's wifi and not through iTunes. I can listen to shows through safari but would love an app that I could us to subscribe and download podcasts i. Anyone no of an app? Thanks Guys

There's an app in Installer (in Multimedia) called Mobilecast, which let you do exactlly what you mentioned; download and listen to a podcast directly from your iPhone.
The only problem (my opinion) with Mobilecast is that it doesn't play the podcasts in the iPod-app, but use an own player.
