'Smart 3G' Will Help You Save Battery Life
Battery life is precious and we all love to save it when we can so our iPhones stay alive as long as possible. One way to do this is by disabling wireless radios when they arenít in use, but unfortunately that requires cumbersome effort. Thatís why iOS developer Itay Brenner
invented a new jailbreak tweak dubbed Smart 3G
Smart 3G is going to make life easier for you by automatically managing your wireless radios in the background. When you are on a Wi-Fi network, Smart 3G can automatically disable all cellular data so those cellular radios arenít draining your battery unnecessarily. As soon as you leave the vicinity of the Wi-Fi network or you turn Wi-Fi off, Smart 3G will automatically re-enable your cellular radios so you always have an active Internet connection.
Being that you will always have an Internet connection, you will be able to continue iMessaging your other friends even when the cellular data is off. You can also send SMS to your friends while your cellular data is turned off, but you cannot send MMS. Voice phone calls can also be sent with cellular data turned off.
The part of the tweak that is most appealing is the automatic transition from Wi-Fi to cellular data. The tweak is very fast at changing between radios and in turn, your Internet experience will feel seamless while it saves your battery in the background.
From the settings application you will find a preferences pane for Smart 3G with two simple options Ė 1. enabling and disabling the tweak; 2. disabling data, but not 3G. By default, Smart 3G will disable both cellular data and 3G (2G also) from the Cellular options in the Settings application.
If you find yourself always short on iPhone battery life, this tweak might be able to help you out a bit. Give it a try!
