downgradeable

Is White PSP Slim able to downgrade from 6.10? Or able to still put a cfw that still has all the games work?

Hey :) Ive read stickies and some general guides/tutorials but some use old information.... Basically I have a PSP-3000 (I remove the battery and it states and it is a Model PSP-3004, 4 being the region) and it is on 6.37. AFAIK, this combination is unhackable. BUT Googling I see its possible...
