Switching to 2G instead of 3G saves battery lifetime.
Unfortunately it isn't possible to change the 2G/3G Settings on Android directly via the API.
So this small widget was created to make changing your data network as simple as possible.
Instead of navigating through many different menus this widget enables you to reach your devices "Mobile network settings" to choose if a 2G or 3G network connection is used with just 2 clicks!

Please don't complain that it doesn't change your 2G/3G Settings directly --> this is a widget to bring up your "Mobile network settings".
