I can't seem to find the answer to this anywhere. What is the difference between having 3G enabled or disabled while the Cellular data is turned off? I am not asking what the difference is between cellular data and 3G so dont waste your time, I understand what they are. My question is what is the difference between having 3G enabled/disabled while cellular data is off. It seems to switch networks if you toggle 3G off, but with the Cell data off does this make a difference in the battery life or talk time?
