INCREASE YOUR BATTERY LIFE. This is a widget to toggle the data connection on/off. Disable the data connection when you don't need it, it will increase your battery life.
* This is a WIDGET, you can't find it in the App list, but in the Widget list. To add it to your home screen, push "Menu" button on home screen, select "Add"->"Widgets"->"DataSwitch".
* For Android 4.0: Android 4.0 has a bug, Widgets sometimes don't appear in the widget list after installation, in that case, reboot your phone, then you will find it in the widget list.
Sorry about the annoying AD, I earned some money with it but not like it. So the AD is removed from the new version, as well as the unnecessary permissions, only access/change network state permission is required as the previous versions. The apk size shrinks to 17k again.
