CoolSwitch 3G Switch is a free utility & tool app developed by Nine Developments for Android. As the name suggests, this application allows users to enable or disable their 3G connection with ease. It is compatible with Android 2.2 and above and has been tested on various versions of Android. CoolSwitch 3G Switch also offers the option to change the icon image from three possible images. The widget provides alerts for three possible states: enable, enable but not available, or disable. If you encounter any problems while using other versions of Android, the developers invite you to let them know so they can fix the issue.
