Yea, I'd like to know what this "sorted" means as well...
Does it mean that Sony took note of all MAC addresses of PS3's in OFW 3.56 v1+? Or is it that the Keys and loaders were changed? I know they were changed, just don't know when they were. From what I understand, I'd say that it means the loaders were changed, and keys signed in 3.56+.
As for staying on topic, I think that a 3.56 downgrade should be worked on by one team, since the keys are out, even though it's 3.55 with slight changes in security. Many people would appreciate this, as 3.60 is going to take a while to develop a downgrade/CFW because the keys and loaders were definitely changed and no longer use the metldr or the other ldr (forgot the name, sue me like Sony likes to...).
I know quite a few people that would appreciate a 3.56 something or other, because of the changes in 3.60. Either way, Sony's starting to crack down, but I don't think that's going to stop people from starting over with 3.60.
