Where is the power control widget?
The handy Power Control widget is placed on your home screen by selecting Menu > add > Widgets > Power control. It can be moved to any of the three home screen panels by holding down on it for two seconds, at which point it will increase in size slightly, and can then be moved and placed where you want it. Use this control to save battery power by quickly activating/de-activating the WiFi, Bluetooth, and GPS as well as adjust the screen brightness.
