Just check your settings general for an over the air update. Mine is stalled so maybe it’s no too stable.
If you’re not a developer, it’s harder to find links. These seem to work
Also you will need the itunes beta 2 for it to be able to update to this version, at least that’s what I’ve heard.
I’d like to cut the PC, but IOS5 doesn’t improve podcasts at all. For being so keen on clouds and syncing, it’s surprising they still don’t offer a way to subscribe to podcasts without being shacked to iTunes.
However there is relief! There are quite a few podcast managers available now. I started with Podcaster but soon changed to my favorite, Downcast.
Downcast has been a very stable app with lots of options yet the interface still remains simple. That’s a hard balance to achieve. For each podcast you can override the global options, such as how many to keep. And the built in swipe-gesture controls are fantastic, because they make the app very usable in a car.
So really cut the PC and download one of these apps.
