One common issue people often have with owing a smartphone is that the battery lift is often not as good as desired. There are many ways to extend the battery life of your device, such as lowering the brightness of the display, or switching off mobile data when not required. However, the second option is not ideal as it prevents you from receiving emails or push notifications. It is well known that having 3g switched on has a strong negative effect on the battery life of an iPhone, but it would be inconvenient to switch 3g on and off all the time manually. Todays app allows 3g to be switched on when your phone is unlocked and switched off, returning to a gprs or edge connection when the phone is locked, allowing push notifications and emails to come through as normal without the battery drain of constantly having 3g switched on.

Auto 3g: How to install

1. Make sure your device is jailbroken, and if it isn't use this to jailbreak it.
2. Add this source: http://repo.insanelyiph0ne.com/ using this guide
3. In sources, tap the above source
4. Scroll down to Auto3g
5. Tap "install" and follow the instructions on screen
6. After installing, if when you open Auto3g you get a piracy message, go into settings on your device and switch aeroplane mode on, then back off again. If this does not remove the message switch your phone off then back on again.

The app itself is quite self explanatory when you start using it, but if you have any problems contact me below or via twitter @nkbish0p.
