The iPhone 3G is an Apple phone that takes advantage of 3G technology to make face-to-face phone calls and provide high-speed Internet browsing. Changing the battery of your iPhone 3G is not as easy as with other phones. With other phones, the battery can be accessed easily by removing the back panel of the phone. To access your iPhone battery, you will have to open the casing and carefully remove the motherboard before you can change your battery.
