I replaced the display assembly this weekend, but when I was attempting to reinstall the logic board (step 21 of the guide, in reverse), a small rubber bumper came loose from 'somewhere' on the board (I think).
Here's a picture of the bumper (with the broken screen as a backdrop to give you a sense of proportion). Can somebody identify where it belongs? It's seldom good when you've got parts left over!

It goes on top of the Logic Board, under the two Front Screen Flex Cables. I have seen a couple of iPhone 4 without this installed or just missing and they functioned perfectly.

Also, notice there is a thick and thin side to the bumper, and the thin side should be on top, or toward the back panel.

That little plastic bumper folds over the top of the logic board assembly where the Digitizer ( Front Panel) cables come up and over. If you look close at the bumper there is a small grove that is the same size as the boards thickness. Its just there to protect the Digitizer's cables from the rough surface of the logic board.
