Okay...I've listed a few of my resources...but my gem is definitely psgroove.com - They are the most up to  with new program releases every day..If you're in the scene, this is where it's at...my main fora for this subject is over @ realhackz.com..so for this projec my resources have been:

http://www.youtube.com/ - had to list it as i wouldn't have tried this without the several proof-of-concept videos i found here

http://www.realhackz.com/ - well they're about more than just PS3 hacking...tho I'd never heard of them until geohot released his public JB two weeks ago..

http://www.psgroove.com/ - they get the info direct from developers first...best ps3 modding/hacking resource out there for sure

now there are a ton (just over the past three days) of ps3 hacking sites...screw these..get ur info from the sources

also..for game backups:
http://demonoid.me/ (rocks! - best resource hands down)
http://torrentday.com/ (sucks ass cuz there's no seeders, but they got EVERYTHING)
http://thepiratebay.org/ (I still love these guys! - not a great ps3 backup resource tho)

---------------
EDIT: realhackz.com are being some lame ass bitches no better than Sony.....they're fucking charging to view forum posts..i hope they choke to death on Sony's cock!
