I tried to use this app called CPU Tuner because a friend said it could toggle data to 2g while the screen is off. I thought that was save battery, so I tried it. But the toggle doesn't work on the TB because the developer hasn't worked on it yet with LTE. So, I am wondering if there is another app to toggle the TB to 2g. I am assuming not because even through #*#*4636*#*# I can only get 3g. Just curious if there is another option.
