In order to make an iPhone there was the basis of cell phones, and telephony and radio in general. And the mining of materials that such tribes may not be in proximity to or be able to mine at such intensities given their low populations and tech levels. For some reason you seem to expect a civilization with the technological sophistication of globalized society with 10,000+ years and billions of people and countless global resources fueling them to suddenly emerge in the small geographies and populations of uncontacted tribes? If you were trying to be witty, you came up short. Edit: or were you trying to play off "negatively affected by the modern world" as, "well they don't have iPhones so they don't have the Social Dilemma, everything's peachy" instead of the blatantly obvious "we destroyed their world and they had no clue" angle...
