My Problem

My brother-in-law gave me his iPhone 4 which had a cracked screen. Later, I found out the screen was cracked because he dropped the phone into his margarita. Whoops! I also discovered the rear camera didn't work, as well as the lock button, proximity sensor, and ambient light sensor. I originally replaced the screen and the rear camera and now aimed to fix everything else.

My Fix

It went okay. I was able to fix the lock button, but the ambient light and proximity sensors still do not work.

My Advice

The iFixit guide is awesome and incredibly useful, but there are a couple of sections that could be improved.

Step 24: The photo used shows the phone without the front screen which means the cables coming from the screen are not pictured either. I had to bend the cables waaaaay back in order to access one of the screws to the power button. I was nervous that I'd break the cable here. A little more advice on how to get out that screw would have been appreciated.

Step 27: There are a lot of details left off here. There are several little foam pads that need to be transferred from the old cable to the new one (I got the cable from iFixit). There's also a little plastic spacer that needs to be transferred to the new cable. When we removed the UV filter with tweezers, we accidentally made a crease in it (it buckled right down the middle), which is probably why this sensor doesn't work anymore. A photo illustrating how to properly remove that would be great.

These issues aside, I'm happy to have my lock button working, at least. And anytime I take apart a gadget and put it back together in working condition is a win in my opinion! Thanks for the help.
