I've searched but can't seem to find an answer. How do you completely shut down an app in 3.0. Originally you could hold the home button down for about 5 sec and it would completely shut down ipod, safari, mail, etc, but doesn't work on 3.0.
Hold down the Home button and Sleep/Wake button for 5 seconds. When the power off screen is displayed, hold down the Home button for an additional 5 seconds.
In 3.0, holding down the Home button for a couple of seconds is reserved for the Voice Control app (iPhone 3G S only).
