George Hotz who’s online username is GeoHot was the first person to ever unlock an iPhone to use any carrier at a young age. He said he had to make it think like a baby since “babies are easy to convince” as he was trying to hack around with settings. He also hacked the PS3.
GeoHot was invited to a meeting with Sony Engineers to talk about how he actually did this attack on the PS3. He said if there was to be lawyers there he would be the “biggest asshole ever” but ended up with a group of engineers. This meeting was an hour long.
