"Anyone" ? Unless you're "in" with the group of devs who create the jailbreaks, you're not likely to know ! I'm sure they try their hardest to keep it secret.
What I did read was if you're already jailbroken, do not update. Duh... That's from Redmond Pie. I'd hope it's obvious to jailbreakers to never update their OS without some investigation.
