Being that we need our iPhone’s everywhere we go, battery life is important. The last thing we want is to need our device in an emergency only to find that the battery is in the red.

Those with jailbroken iPhones may have a new solution for converving battery life, and it actually sounds pretty awesome. We will be upfront and tell you that we haven’t tried it for ourselves, (it should be available on Cydia tomorrow) but the application is designed to turn off the 3G radio while locked (leaving on the 2G for lower power consumption). Upon waking the phone, it turns on the 3G radio again. With version 2.0.3, it goes further by providing an option to let you use 2G for talk while reserving 3G for uses such as when running a designated application like Mobile Safari or YouTube.

We’d like to hear from those of you who have used past versions or are planning on trying out the new one about your experiences with the battery life.
