With the main PCB removed, we get a clearer look at the iPhone 4S' other internal components. Unfortunatley, most of them are glued to the metal frame. To avoid damaging them, I left them in place.
I also chose to leave the Retina display and touchscreen (front panel) attached to the metal frame. I actually removed all the display assembly screws, but it did not want to come loose. As with the other internal components, I left it in place to avoid potentially damaging it.
I did however, remove the vibration motor.
