iPhone OS 4.0 keynote - The highlights

If you missed it, do yourself a favor and watch the rebroadcast of yesterday's iPhone OS 4.0 media event. You can watch via a Web stream or download it for offline viewing on your iDevices as a podcast. If you don't have an hour to spare, you can zip through Steve's slide deck by skimming liveblogs of the event from CNet and Engadget, or check out Gizmodo's piece on iPhone 4.0's best new features. iLounge has posted a transcript of the event including the question and answer session with journalists that followed the event (which isn't included in the Apple video).

Some highlights include:
