Mentioned briefly at WWDC and in more detail during Apple's Surprise and Shine event on September 9, iPhone Handoff lets you use the same phone number across two iPhones; in typical Apple fashion, the feature is so easy it's almost invisible. Once you set it up, all you have to do is unlock the iPhone you want to use, and you're ready to go.
