Just for history’s sake: I wrote iPHUC (and yes I was 19 and came up with that name lmao) and a guy with the nic “nightwatch” who I loved working with was responsible for the initial jailbreak and coining the term itself. I believe he was also responsible for pdf or tiff exploits that unlocked the PSP, too. He worked and lived in South America possibly at a university … but that’s all I know.
It was a really fun time and I learned a lot.
Also, George Hotz endangered the welfare of a few people who had kindly gotten us access to some documentation in Japanese despite repeated pleas not to do so. Very frustrating and why the dev team all eventually stopped working on the project.
