Since it has an aluminium body, it's okay for the iPhone to heat up. It usually heats up when you're playing some games with high graphics or if you're using some high memory applications. Using the device while it's charging will also heat up the device.
If you're not doing anything of these above tasks, and you still think it heats up too much, you might want to take it to an Apple Store.
