iPhone 3G power button

is it a "OEM" back cover or a genuine iphone cover ?

does the button go easily down?

im having exact problem if anyone knows

When you took it apart there should have been a small (about 2mm) black metal strip between the button and the switch. I'm pretty sure it was a spring, glued perpendicular to the button, pointing downwards, between the button itself and the wire loop. Gluing it back in in that position gave me the best results.

I didn't see anything like that either. Just the black piece that the button area of the ribbon cable adheres to and that's it.

I know this has been dormant for a while but I'll give my solution in case it's useful to anyone. My fix for this involves a razor blade and no new parts other thatn the new OEM housing that got you into this mess. The reason this happens is that OEM housings are typically all molded after the originals in white plastic. Then to get the desired color, they pain the housing (which you likely know if you own an aftermarket housing. That thin layer of paint around the edge of the hole that the on/off button goes into along with the camera lens hole and headphone jack hole is giving just a tiny amount of friction between the button going up and down. What I did was get a razor blade (Xacto knife will work too) and just slightly trimmed that layer of paint away from the inner rim. For the camera lens hole and the headphone jack hole I bought this tool at Harbor Freight (http://www.harborfreight.com/t-handle-re...) and it works amazing. Don't even apply pressure while turning it inside the hole and it will scrape that tiny bit of paint out and you'll be in good shape.

I cut off a small piece of the foam pad on top of the #4 ribbon and glued that to the button on the ribbon that the actual power button presses against when you push it, and that seemed to do the trick and give it the right amount of tension.

Can anyone post a pic? I have the exact same problem from disasembling and reassembling my iPhone. I'll be going into it again soon to try to fix and would like to have a better idea what to expect.

I don't have an answer. I have a question. My power button doesn't have a retracting problem. In fact. that aspect of it works fine. My problem is that it doesn't turn my 3g iPhone on or off. Is there a ribbon in the set up that could have gone bad and if so, is it available. Help me please

Here are a few tips to getting the button to protrude the case correctly and getting the correct tactile feel.

1) make sure the button you push fits and moves freely inside case slot. I check the fit by inserting button from outside of case to check button engages all the way to button stop lip and can move in and out.

2) try pushing stop button on flex cable by itself with thumb and fore finger. It should have the correct feel.

3) very important! Make sure stop button (on flex cable) has the raised bump, in the clear button cover, is in the center of the button metal disk. If it is not then peel the clear button cover back and put it so raised bump is in the center metal disk.

4) put it all together and you should be good.

5) if button you push sinks when pushed and does not come back out. Then you might have to shim face of the button where it pushes the flex cable button. I use very small piece of electrical tape.

I hope this helps, I have had lots of problems fitting the stop buttons so they feel like they should. That's why I have so many tips. lol
