Can't identify 4 parts after iPhone 4s disassembly

From left to right:

• I'm not positive about this one, it may have been stuck to the mobo, but I'm not sure to what end, or where.
• This looks like a rubber gapper, which sits under the EMI shields, to help cushion the chips against shock. I don't know which shield this one goes in, but I believe there is a space it fits in the underside of the mobo.
• This is a rubber cushion that fits between the motherboard and the top of the metal frame. it wraps around the edge of the motherboard to the right of the rear facing camera, just to the left of the topmost screw in the connector cover plate.
• This is the antenna grounding finger that goes to the right of the connector cover plate, over the stand-off screw, with the small screw holding it in place. The curved bit fits into the frame, and grounds the finger, and the flat arm sits on top of the antenna cable, after it's been clipped into the motherboard.

Hope this helps, if I can clarify anything, let me know.
