This shows the piece installed.

Just fit it over the logic board. Its in the red rectrangle.

It's not necessary for the function if the phone. It's simply to protect the screens cables from the edge of the phones logic board. A small piece of electrical tape over the edge would work just as good...

Is there a place where I could purchase that black piece? When I disassembled my phone, I saw some black piece fly out and I thought it was something else, so I didn't worry about it. Now I can't find the piece...

here where the black rubber piece speaker of iphone 4s goes!

Where and how iPhone 4S rubber square piece speaker dropped goes

No that peice isnt the same as the pic he showed ive just stripped mine and it goes at the top where the barcode is to stop cables rubbing

I have taken the phone apart a couple of times and have not come across this part. It looks like it is maybe a structural piece that goes along the inner frame of the mid body. Chances are your phone is probably just fine without it.

I have the same here, small rectangular black rubber. does your iphone works perfectly ?

i have the same thing here too and don't know what to do with that piece. seems to have come out when i took out the speaker section.

Memed is correct - that piece of rubber protects the ribbon cables from edge of the logic boardso they dont crack.

Thanks Anthony...is there a way you could illustrate how to install it?

Thanks!

Peculiar, I've taken my iPhone 4 apart with the utmost care and have not ever noticed that little rubber piece. Wonders if mine is there at all. -Shrug- my two cents.

this part is out of my iphone 4. i don't think it has anything to do with my iphone not being able to find any service though.

Haha.. Thank goodness I wasn't the only one. Googling "iPhone 4 lit" predicts "little piece" which I found more than amusing. Truthfully I didn't think I would find an answer but sure enough, right back at iFixit. Thanks so much for the photo Anthony. Much help..

i threw mine out because i had no idea where it came from ,now i keep loosing signal ???

It seems like not all of the phones have this part i did one today and it was not there and im very careful about being sure that i dont lose this part.

Took my phone apart last night and this piece fell out. I reassembled without it, and now the screen doesn't work at all. Any chance this could be responsible? I know the phone is on because it vibrates when plugged in, and the voice command works, but nothing on the screen shows up.

I'm going to take it apart again and check for breaks in the LCD cable and put this piece back in. We'll see...
