Undisclosed iPhone features?

Over at AppleInsider, there's an article about a video team from Actioncorp who went over Steve Jobs’ keynote speech with a fine-tooth comb to find hidden features on the iPhone. Now that's dedication! Apparently they broke the video down frame-by-frame, looking for interface bits and pieces that might signify exciting undisclosed iPhone features.
Among their findings, a ringtones tab makes an appearance, which the group suggests may mean iPhone users will have a lot of flexibility in that area–maybe even the ability to browse and buy ringtones from the iTunes Store. The calendar app also was mentioned, with a brief description of what action each button might do. Another possible feature from the video findings is possible GPS directions via the Google Maps feature. Apparently, the video team noticed extra buttons on the map tool, indicating that iPhone users would be able to get traffic indicators and possibly directions to their destination. You can watch Actioncorp's video of these findings here.
While these possible features are entirely speculative, it’s an interesting video and we highly recommend you take a look if you're as interested in the iPhone as we are (not likely!).
What do you think? Does Apple have a secret plan to offer iPhone ringtones at the iTunes Store? What other features do you think we'll get with the iPhone? Are we wasting our time looking at specualtive iPhone videos?
