Apparently my Otterbox case couldn't protect my phone from a 2 foot fall. My LCD had dead columns of pixels and flickered after the fall.
After successfully fixing my PS3 because of the guidance provided in iFixit's video walk thru, I figured I would come back to iFixit.
The parts arrived and were well packaged. I installed the repair manual app on my iPad and followed the instructions and figures provided. The directions are short and to the point and the pictures are clear enough to zoom in and see more detail. During the entire screen replacement process (2 hours) I never felt lost.
Now I'm entering this review on my working iPhone.
Anybody that is ready to perform this surgery on their iPhone needs to understand that apparently Apple has a surplus of glue and isn't afraid to use it. I spent 2 hours repairing my phone and 1/4 of my time was spent slowly prying and loosening my battery from the case. I would pry with the plastic tool provided and would slice the glue with a dentist pick kit I use for circuit card assembly.
