Hi folks! If you are like me, you use your iPhone for everything! I consider it a tool in my computer consultant repertoire that I use to get my work done.
I can use it for pretty much anything. However when you use something that much, you obviously will have concerns about battery life usage. Well Auto3G is an app that automatically switches off your 3G when you are not using your phone so you save on battery power.
Auto3G is an app you can get from Cydia if you jailbreak your iPhone. If you have a jailbroken iPhone I encourage you to go out and get it now!
