i apologize if this was already posted, but i found this little gem in recording video. if you double tap the screen, it will zoom out to a wide screen mode. similar to ipad. didn't do this on old iphone.
Yeah, I noticed this. The reason you can do it now is because it actually records in standard 1280x720. Before on the 3GS I believe it recorded in the same aspect ratio as the screen itself, 1.5.
I will always record like this so I can see everything I'm capturing.
