The arrival of video functionality in the next firmware iPhone OS 3.0, does not present almost no doubt. The famous site MaRumors sticks to it by broadcasting a screenshot of what would be the photo / video interface available in the next OS.
As you can see, a light switch is set up for switcher between photo or video mode. A red button will also replace the classic shooting button and will start video recording.
We discuss it on the forum.
