Podcasts App-No sync with iTunes iPhone 3G

Did you try in computer iTunes with your iPhone connected and selected, Podcasts tab, check Sync Podcasts?

Exactly the same as my case, just download podcast app and all my podcast should correctly at podcast app, however after playback, won't sync to music app / itunes. I do love the UI but without sync read/unread status, no way to swtich to podcast app.

Yes I do have sync podcasts enabled and I set everything up with the iPhone connected via USB to the PC while iTunes was running.  As I've been reading around other places on the web it seems to be a common problem that there is a "disconnect" between the podcast subscriptions you make in iTunes vs. on the iOS devices.  Bummer, I hope that they improve this before iOS 6 or maybe even sooner via an update.  As it is now, managing 2-3 separate lists of 20-some-odd podcasts on multiple devices is just not going to be possible. 

I have the same problem. After installing Podcasts I have a podcast in itunes on my imac, the same podcast in itunes on my iphone and now a 3rd copy in the Podcasts app and they are all independent of each other ie. they do not sync. Podcasts on my imac in itunes do not sync to the podcasts app, but do sync to itunes on my iphone.

If I switch off podcast syncing in itunes on my imac it removes all podcasts from itunes on my iphone but not from Podcasts. Switching on syncing, puts them back to itunes on the iphone but not in Podcasts.

I'm not sure if it's supposed to work this way. It's unclear to me from other posts on various other websites. If this behaviour is deliberate then I fail to see how Podcasts is useful for me. I listen mostly to podcasts on my desktop computer and sync to my iphone when I go out. I don't really see the point of managing podcasts solely on the iphone using Podcasts.

Same issue here. 

Does it actually have 2 copies of podcasts.  Doesn't look like they share the same itunes library.
