You've made it public, the ****ers are already closing in, they'll hunt you down like a ****ing beast, you can't just leave for three weeks, they'll be waiting for you when you get back goddamit MAKE HASTE AND FLEE!!
I can't see how the keys will lead to a jailbreak either as they are not the private keys.
I'm guessing this will allow just allow us to decrypt things complied for 3.60, and then we can edit and resign using the private keys for 3.55 ect.
So the end result looks to me more like a solution to get the newest games to work on 3.55 CFW.
As much as this may leave 3.56, 3.60, etc. people out of the game (for now), this would still be a great leap forward as far as I'm concerned. It would at least renew a lot of hope for those losing their heads about whether upgrading is the right thing to do.
