I had issues with my home button not working which turned out to be due to the cable leading to the two gold contact pins lifting up off the speaker assembly (the cable is immediately to the right of the red circle in this image). Pushing this cable down with a spudger so that it stuck back to the speaker assembly fixed my home button. No idea why this works though...

This should be in the guide. The front panel is actually recessed a bit here making it much easier to get a tool in at this point. No way I would have opened it without this tip. Thanks!

I found it easier to open these clips using the pointy end of the spudger rather than the flat end. Just slide it in against the side of the case and the clip will pop off.
