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: http://img263.imageshack.us/img263/8572/...
- 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: http://s12.postimg.org/440dmyrlo/image.j...
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.
