After dropping my iPhone probably once a week for 2.5 years the last drop finally did some damage. I shattered the rear panel. Knowing this wasn't a very expensive component I decided to try to repair it myself.
The repair went great. Of course its only two screws so how could it not go great. The guides and tools were perfect for the job.
If you're thinking about replacing your iPhone's rear panel I fully support going for it. Its two screws and your in and out. Its literally a 3 step process where 2 of the steps are removing and replacing screws.
