Et voilà, we have the mainframe with three individually removable modules. Little icons next to each one indicate what they do:

Headphone jack, earpiece speaker, and front-facing camera module

Rear-facing camera module

Microphone module

We also discover a proud little map showing the sources of the conflict-free tin and tantalum used in the phone.

Amazingly, up until this point we've only needed one tool: hands!
