Fantastic, worked perfectly. A couple of tips:
* The ribbon cables have a plastic housing on the underside, which contains two rows of metal teeth which bite onto a similar row of metal teeth on the logic board itself. The tiny ribbon cables e.g. 6 have a small round metal 'popper'. Both types can be simply levered off with the spudger, and then pushed back on with your finger (i put the spudger beneath the whole ribbon cable on number 1, to ensure I was pulling up the whole housing and not just the spongy bit of foam with a sticker on that lies on top of the ribbon.
* Another tip I have is that if you don't have a magnet to store the screws on then a bit of blue tack (silly putty) words well. Useful for when you drop the screwdriver on the desk and everything else goes flying..
* Especially when replacing ribbon 3, I found I had to stick the phone to the desk to stop is sliding while I put the cable into the clamp housing using tweezers. Pretty fiddly but quite satisfying when you get it right. Note that it doesn't go all the way in; you can still see a couple of mm of orange poking out when it is time to clamp the tab down.
* Very happy with iFixit; I've ordered twice now, and both times I have received my order within a week. And I live in China. Top notch!
