Marcan (of Asahi Linux fame) has talked about it many times before. But an abridged version

Fail0verflow demoed how they were able to derive the private signing keys for the Sony Playstation 3 console at I believe CCC

Geohot after watching the livestream raced into action to demo a "hello world!" jailbreak application and absolutely stole their thunder without giving any credit

If they demod something then they released it publically and it was fair game?

In any case he absolutely did credit them, it's easily verifiable: https://web.archive.org/web/20110104040706/http://geohot.com...

Sony sued them both, afterall!

This apparently worked pretty well for him, as I still remember him primarily as "that guy who hacked PS3". Some people let someone else do the hard technical core, then do all the other easy but boring stuff and claim 100% credit.

I remember geohot as being one of the people who developed a fairly successful jailbreak for iPhone. I understand that iPhone jailbreaking is often standing on the shoulders of predecessors, but I believe he does deserve significant credit for at least one popular iPhone jailbreak.
