Here ‘s another very basic tip for users of iPhone OS 3.0, but one that I often forgot about until recently.  Prior to OS 3.0, to ‘force quit ‘ an app (force it to close when it was unresponsive or hung up) you simply held down the Home button for 5-10 seconds “ after which the app would close and you ‘d be dropped back to the Home screen.

In 3.0, with Voice Control being invoked by holding down the Home button for a few seconds, there is a new method that you have to use in order to force quit an app.

The new way to force quit an app under 3.0 is:

• Press and hold the Sleep/Wake button at the top of the iPhone for a few seconds until you see the ‘Slide to Power Off ‘ message come up.
• While that screen is up, don ‘t slide to power off and don ‘t hit ‘Cancel ‘ “ just hold down the Home button for around 8 seconds until the app is closed and you get dropped to the Home screen.

That ‘s it.  Not quite as simple as before 3.0, but still more than easy enough to do “ and a good thing to know when you have misbehaving apps.
