While the rest of us wait around for the official release, some lucky Devs have tossed caution to the wind and ignored the binding clauses of their NDA to leak some screenshots of the upcoming iPhone 2.2. firmware update to the world. Among the goodies include a look at a redesign of the App Store to make it a bit more intuitive. The big news, however, is the addition of a Podcast tab to the iTunes store. Providing the ability to download and subscribe to podcasts on the go should mark a significant feature addition, and even better yet it appears that any podcast under 10MB will be available over the 3G network. Similar to the App store, files exceeding the 10MB limit will only be offered over Wi-Fi, but given the impressive strain on AT&T’s data network, we can’t say we’re surprised. As always, this is subject to change before official release, but the shots look polished enough that we’re confident in getting our hopes up for the final iteration.
