With your iPhone's hidden screenshot utility you can grab stills from any video you can view. This includes YouTube vids, iPod vids, Net vids, email vids, and those stored on your iPhone with apps like Air Sharing. There's a size restriction: the images will be 320 pixels high by a width of up to 480.
- While viewing a video, tap the screen to call up the controls.
- When you get to the frame you want, tap the Pause button.
- Tap the screen to hide the controls.
- Hold the Home and Sleep buttons at the same time and release them.
- The images are stored at Home/Photos/Camera Roll.
