Whew; experienced with Mac repair, but this was my first iPhone. The stupid adhesive tabs suck, but a few minutes with a heat gun fixed that. Managed to have one of the insanely small screws pop out of the tweezer and land in the rug at my feet; after a few minutes trying to spot it, I slapped my forehead and grabbed a couple of hefty magnets from my fridge and waved my hands over the area; I didn’t even notice when the screw was picked up, but there it was on the magnet when I was done. The last sticking point was that %#*@ multi-touch lcd cable kept popping up; angling the back forward while holding the cable connector down until the two top screws to the shield were back in helped; as it was, it took five tries (thus the bobbled screw, above). Getting those teensy tiny screws back in was the harder part of this. Calibrating battery now! Thanks again, iFixIt!
