  • '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!

      sorry. typo. iPhone 4S with IOS 5.1.1..... im running auto 3G ver 2.0.3 working like a DREAM.

      p.s: just the feature of running my 4s on edge upon lock increases my battery life to up to 2 days(also note tht i have intelliscreen so i do most of my social networking through the lockscreen wich is on edge īcause it switches back to 3g upon slide to unlock)... so experiences may vary

      I used to have auto3g. but it would turn off 3g when using the charger in the car. Didnt like the buzzing on the speakers when sending a text.

      This tweak interrupts a call when you lose WiFi connection during the connection!
      How the developer could be so irresponsible?
      This should be the first thing to predict & implement...

Auto 3G will change from 3G to E (edge) connection when you lock your phone(in a user determined time after lock) and switches back to 3g seamlessly as soon as you swipe to unlock, it also gives the configuration options to prioritize radios, so where there is wifi available, it will turn 3g off but maintain cellular connection via E[and after switch back seamlessly]; you can even set to keep on E (edge or 2g however you want to call it) except for when specific applications that you determine are running, ect ect....

      Auto 3G.. has done wonders for me...

      in fact... here you go..
      ModMyi.com | Auto3G

      i believe the above is an old package tho... Because i have it installed on iPhone 4S 5.2.1 and work amazing
      would love to see this function with smart3G, hope the developer will add this in the next release.....
