This repair took me longer than advertised, and I had to do it twice to get the camera back working properly. My tip for "magnetizing' the screws was to dip the screwdriver head into a glue mouse trap ever so slightly. This put just enough adhesive on the end to enable me to get the screws back in place before tearing my hair out. I also put a white cotton cloth down on my workspace so I would not lose any parts and that turned out to be a good thing. As of now, the new battery on this phone is performing better than the one on my new 4s.
Agree with this comment. Prying the battery up from its adhesive was the hardest part of this repair, and yes, I did break the spudger thingy.
