How do you properly charge an iPhone?

There are two ways to charge your iPod touch. When you get an iPod touch, it comes with a cord to connect to the computer. The first way to charge it is to plug the iPod into the computer using that cord. Also, some stores sell wall adapters for iPods or iphones. With this you just plug that same cord into the wall with the adapter, then plug the other end of the cord into your iPod.
