The iPhone 2.2 update was mainly just a bug-fix release from what I can tell. But one feature it did bring was the ability to download podcasts right on your iPhone, which is awesome! I use MobileMe to keep my iPhone synced, so there really is no reason for me to ever connect my iPhone to my laptop except maybe to upload some music from time-to-time. I have to admit, I’ve pretty much stopped listening to podcasts since I got the iPhone because I can’t be bothered to dig up the wire to do the sync.
With the 2.2 update that came this week, you can now download the latest from your favorite podcasts right through iTunes.app on the phone. Just go to iTunes.app and search for the podcast you want. Unfortunately it isn’t smart enough to make it download the latest from the podcasts you already listen to. Anyhow, when you get there there’s now a “Download” button. One click will start the download, which will even continue if you close the iTunes.app. When the download is done, you’ll see the podcast in the (you guessed it) “Podcasts” area of the iPod.app.
This update is probably the death-knoll of Podcaster.fm, but for the rest of us, we can all breath a collective sigh of “FINALLY!!!!!!”
