I'm not saying that the FBI story isn't true, but so many comments here just assume it to be 100% factual - there's no evidence that it was taken from the FBI vs found on a USB Stick in the garbage.
It's a big story, yes, but I think maybe a deep breath is in order before we all accuse the FBI of leaking/losing/stealthily acquiring something!
(I'm not a US Citizen, btw)
Besides, what's the big deal... if they have nothing to hide then they have nothing to worry about!
What bothers most is that this data exists at all, and what it's used for.
Though, it must be curious why AntiSec have had 12 million UDID's, but only now are releasing them. Also, no one else from AntiSec is corroborating it?
