Former software engineer Scotty Allen of Strange Parts created an awesome video that follows him on a journey as he builds a working iPhone 6s 16GB from scratch “entirely from parts bought in the public cell phone markets in Huaqiangbei, China.”
You might wonder why I chose to make an iPhone 6s and not an iPhone 7. I had two reasons.
