A set of 11 videos describing repair procedures, tools and reference material for iPhones, apparently produced by Apple for internal use, are in the wild. Motherboard:
Arman Haji, who uploaded the videos to his YouTube channel, told Motherboard he initially saw them posted to Twitter. “When I saw these videos I downloaded them out of curiosity, and when his account got suspended, I wanted people to still see them, so I uploaded them to YouTube,” Haji told Motherboard in an email.
