Other tweaks include the ability to return to the phone's home screen with the touch of a button--which is helpful now that users can fill their phones with multiple screens full of applications.
Fill a bottle with cool water, screw it into the carbonator, press the fizz button five or six times, add the mix to the bottle (I recommend doing this over a sink), close the bottle and shake a few times.
Rather than fill the device with bloatware apps or overlay a custom UI, Sprint's installed a software button that takes you to a store exclusively designed for Sprint's new Android devices.
