When you buy an iPhone, you are going to need at least two accessories: a decent case and a battery extender. There are other accessories you can pick up but those two are a must have if you want to keep your iPhone safe and get the most out of it. iPhone 4 battery cases give you the best of both worlds. They can keep your device safe against scratches. They also let you use your iPhone for longer on the road. They save you the trouble of having to carry multiple accessories with you.
