now that the those crazy awesome hackers have released an untethered jailbreak for the iPhone 4s, we finally have a way of saving our iPhone 4s battery a little bit with the useful free feature called "SBSettings" from BigBoss, with this you can disable your 3G data and using edge to save battery
as apple didn't add it in with iOS 5. i am aware that they are adding it in iOS 5.1, but we might not see a jailbreak for that firmware so this will have to do till then
