If you work there and can be of help, definitely Contact Us and we will reply with more details... the documentation/files we are currently seeking from someone 'on the inside' at IBM isn't something that should be discussed on public forums.
Although GeoHot has had great success in the past, I'm willing to bet the ps3 will be a challenge, even for him.. especially alone. Here's hoping he joins up for a united effort... or at least shares his findings.
I don't think the ps3 will be unlocked this year. I sure would hope so. But it's like 3 months remaining, and I think that by then the dev team will understand the dev tool and could make progress. Can someone give Geohot proper tools so he can go further!
