Incredible guide! Using this and the repair kit, I replaced the damaged screen on my phone with minimal trouble. The guide is right; there are a number of small, very small, and - ok - downright tiny screws. I didn't buy the cool magmat so I used a big piece of paper and deviated from the guide a bit.
Since there isn't really any overlap between the LCD screen guard, the front camera assembly and the home button I replaced each one individually instead of disassembling the entire phone first. I got about halfway through the camera assembly but then removed the guard to give myself better access. I also felt more comfortable manipulating the new part with a big metal backing plate on it, call it peace of mind. After getting the backing installed I finished up the camera assembly then moved to the home button. At any given time there was a minimum of screws to be lost or confused with others.
As a last note the most worrisome part for me was the contacts had to spend a while carefully manipulating them.
