A peek at the underside of the home button.

Legend has it that if you press the home button from this side, your iPhone will actually be sent to the moon (we refrained from testing this theory).

Again, notice the white and red liquid indicator strips.

Siri, please stop staring at us like that. Come on, you knew we had to see what was inside; we're curious, ya know?

To get Siri to stop staring, we recruit the help of our plastic spudger to remove the second camera.

The front-facing VGA camera is good for exactly two things:

• Communicating via FaceTime
• Taking self portraits a la Myspace Facebook Google+

We have reached the end of our journey. We are happy to announce that not a single trace of any Cyberdyne Systems components were found...it seems for the time being our judgment day is not upon us.

iPhone 4S Repairability Score: 6 out of 10 (10 is easiest to repair). Very little has changed from the iPhone 4 in terms of repairability.

• The iPhone 4S is still held together primarily with screws and limited adhesive.
• The rear panel and battery are both easy to remove and replace (provided you have the right kit and/or correct screwdriver).
• Apple is again using Pentalobe screws to secure the rear panel and keep people out
• The LCD and glass -- a carryover from the previous generation -- are fused together, making cracked glass repair more costly.
• Lots of smaller components are soldered to one ribbon cable, increasing the cost of repairing just one component.
