Gizmodo has a very helpful article that gives detail on the new features in iPhone 4.0. There are items here that I didn't see in the first wave of coverage, such as local notifications, custom backgrounds (that is, persistent backgrounds, not just the lock screen), 5x zoom, iBooks, and more. Plus, the article has a number of links to even more detail. They've gleaned info from a variety of sources, including Apple's developer guidelines.
