If I try to jailbreak my 3.60 PS3 with CFW 3.55, what will happen to my PS3?

I've been searching all over the Internet for a legit 3.60 jailbreak, but I'm now sure it doesn't exist, and there is now way to downgrade from 3.60 yet. I'm just trying to see what would happen before I did something stupid or made a mistake i would regret....
