Watchoo lookin' at trick
The actual 4S camera is really good and capable of recording HD video, so all you'd need to do is figure out a way to set it up and record yourself. Since it has auto-focus that shouldn't be an issue either. Now, I'm not sure if something like this exists or not but if you could somehow access your iphone camera through your computer, and then see yourself on the computer screen as it records that would be really helpful for you as well.
