I just got a psp 3000 and it is on firmware 6.60. I know that both 6.60 and 6.61 are hackable and have multiple recommended cfw for them. However as the psp seen is dwindling there isnt a lot of info available on the optimal choices. Should I stay on 6.60 or is 6.61 superior? Which cfw is the most noob friendly for someone who knows nothing about psp and just wants to play backups? Also what is infinity? I read it allows permanent cfw? Thanks
