Tried my hand at sketching a possible future iPhone design. I tried to eliminate the hardware/software distinction (think Apple Watch) and allow the iPhone to entirely assume the identity of whatever app is launched. The power button on the side has become the home button - it can be held for an extra second to switch the screen off. The headphone hack has been removed, dual speakers have been introduced, and the camera has become flush with the body. The back surface is a matte black, and grippable. The image with the Music app icon shows how the animation would look as it's launched. Parallax makes the icons look 3D, and of equal thickness as the phone itself.
