Apple has posted a new ad for its iPhone 6s and 6s Plus, highlighting all of the new features that come with the new phones. With the refrain of "the only thing that's changed is everything," the ad shows that though it looks like last year's phone, everything inside has changed.

The ads shows shows off the new 3D Touch display, along with Siri's improvements and the new rose gold color. You'll also see the new, 12MP iSight camera in action, as well as the use of the display as a flash for the front-facing camera. To top it off, the ad features cameos from actor Bill Hader and pop star Selena Gomez.
