How to Switch off Your iPhone 3G (or) 3GS

To switch off your iPhone  and iPhone 3G and the iPhone 3GS, is a very simple process but seems difficult as there is no specified button like in that of Nokia which shows the Red button telling that it is a switch off button. The process of Switching of your iPhone is to:

1. Hold down the Sleep button for 5 seconds.
2. A Red Slider appears showing “Slide to Power Off” and a “Cancel” button in case you dont want to switch off the iPhone.
3. Then you have to slide the slider to Switch it off.

Situations where it is a must to switch off your iPhone:

1. In case an Application gets stuck.
2. In case you have very low battery.
3. When you install a new software which requires a Restart.
