Noobz? Maybe not Noobz, but definatly team C+D and / or the Prometheus Team. Noobz are more into exploits found in games and unlocking PSP caperbilities.
There's been some discussion over at the PS2Dev forums about how they are going to plan to unlock PSP3000. If Pandora isn't going to do it, then they're thinking of other methods. However, I'm going to quote on the great TyRaNid here:
There is certainly undisclosed exploits

So I guess the brains of the PSP comunity have it all covered. Note the plural use. "Expoit
s".
I'm sure the PSP scene will live!
