We have found them! Just as Apple promised, there are more microphones residing in the top of the device.

First, we find the front facing top microphone, presumably for FaceTime and speakerphone capabilities.

And on the back? It's starting to look like a triple microphone! The rear-facing microphone partners up with the rear-facing camera for recording video, and is also used for canceling out background noise when on calls.

iPhone 5 Repairability: 7 out of 10 (10 is easiest to repair)

We're quite happy that the glass/display is the first thing that comes off the iPhone 5. The majority of iPhone repairs are due to a shattered front glass.

The battery comes out with a bit of prying once the front panel is removed.

The iPhone 5 still uses Pentalobe screws on the exterior, making it more difficult to open the device.

The front glass, digitizer, and LCD are all one component, thereby increasing cost of repair.

Lots of smaller components are soldered to one ribbon cable, increasing the cost of repairing just one component.
