I was impressed when I saw this the other day and I agree it is really the result of the person making it and the equipment he uses to move the iPhone even more so than the iPhone itself. But the whole "edited entirely on iPhone 4" should have a caveat. I believe he said he offloaded the video from iPhone to his computer to do some audio work then loaded it back onto his iPhone for the editing in iMovie. iMovie for iPhone lacks the audio customization needed to add layers of soundtrack and voice recording from a separate device. It just adds one audio to the entire movie. But the quality for an iPhone is great IMO.
Here is his quote:
"Michael Koerbel 3 days ago
ADR recorded on the iPhone in a closed car, then clips were extracted and added and mixed with the score track prior to syncing in iTunes and putting back onto the iPhone to be used in iMovie ... it took us a bit to figure it out, but it worked."
