pre-rumor run-up. Now get outta here, your iTunes update awaits.
Update: Added some screenshots of the most notable new features after the break. The Street View implementation seems solid though we miss the compass feature found on T-Mobile's G1. Also, the real-estate saved by moving the Google search field next to the URL field in Mobile Safari is a welcome and obvious change. As to auto-correction, well, that's personal taste. Tipster Vizcaya also noticed that Apple added a new option to rate an App when you delete it from your phone. You can also view multiple screenshots of applications available in the App Store.
Update 2: The other big update, Podcast downloads, works just as you'd hope and should further promote the spontaneous isolation we all crave. A few shots of that added after the break.
