The iPhone 3.0 OS upgrade has brought more control to the fingertips of the device's user. If you are listening to music on the iPod player, watching a video or a YouTube clip, you can control the speed of scrubbing by holding the button on the seek bar. With your finger on the bar, you will have "Hi-Speed scrubbing". Dragging your finger down the screen will change the scrubbing to "half-speed". Slide down a little more and you will running at "quarter-speed", followed by "fine" which is the slowest option you have. Another time saving feature that Apple has tacked on to the new operating system.
