All black rubber piece locations of the iPhone 4S

Thought I'd make this post as there is no single place where all of them are mentioned.

- Thin slender rectangular black rubber piece with slit:

fits to the edge of logic board at the top left where the cables are bent, to protect the cables from any damage from the sharp edge of the logic board. Marked red, on the left of this picture:

- Very small thin square black rubber piece:

is placed on the cable between the dock connector and the microphone in order to fill up/serve as a spacer, I think in order to isolate the cable from the vibrations/noise caused by the loudspeaker.

- Small thick square black rubber piece:

is stuck on the right open contour of the loudspeaker in order to fill up/serve as a spacer at an empty space next to the rubber microphone inlet, I think to isolate it from any noise interference or vibrations. See:

This guy's post helped me find out: Where and how iPhone 4S rubber square piece speaker dropped goes

Either way, it's not a primary element of the iPhone 4 or 4s, so it would probably only cause more wear due to insufficient protection over a long period of time.

Anyone feel free to add any more locations, remarks.

The 4th thin rubber piece is to the right of the camera and hides one of the screws as well as a ground clip for the camera held in place by that screw. The ground clip is installed parallel to the top of the case and the top of the processor board. Be careful not to twist the ground clip when reinstalling and tightening this screw. I use a flat-blade screwdriver to hold the clip parallel while tightening the screw.

Another note. I have been trying to figure out the orientation of the "slender rectangular black rubber piece with slit" (cable protector). I have concluded that the thick edge goes down, by the slight indentation on the face of it. It looks to be the size of the thin 3rd cable in the video bundle, but I don't have a virgin phone to look at to verify this conclusion.
