I have tried the iTunes 7.7 confidential pre-release—which will be required to install the
new iPhone OS—and the latest iPhone OS 2.0 release: 5A345. After a few days of heavy use, I can tell you that both versions are rock-solid. As you can see in the video, the App Store is there—although it's not active yet—along with the new Push data feature, the content restrictions, and the BCC field in Mail, among the rest of the new features. iTunes doesn't change much, but there are a couple of interesting additions, like the "iPhone and iPod touch remotes" option, as you will see in the gallery.
