#12 Change your phone's name, directly on your device

You couldn't do this in previous versions, but iOS 5 introduced the ability to change your phone's name directly on the device. Before you had to do this through iTunes. Changing your phone's name can give it personality. (SAI editor Jay Yarow calls his "Tumor Toy." We dare you to do better.) You have to dig a little to get to this one. Start by going to Settings. Next head to General, and then About. At the top of the page you'll see your iPhone's name—tap it and you can change it to whatever you like.
