https://www.cnet.com/news/iphone-7-headphone-jack-china-strange-parts-scotty-allen/ >Former software engineer Scotty Allen is one of those people. Allen famously made his own iPhone 6s from parts bought at electronics markets in China, so it wasn't a huge stretch for him to pick up an iPhone 7 and decide to install a working headphone jack. >Allen posted a video of his headphone exploits to his Strange Parts YouTube channel on Wednesday, and it tells a tale of determination, electronics know-how and perhaps a tinge of madness. There may be some irony in the fact that the video has come out just before next week's unveiling of the iPhone 8, which will likely remain jack-free.
