@rsm: Yay!
Ironically, that uks.disabled folder looks pretty okay, if not for the fact that it's, well, disabled (by not being named correctly)

. I don't remember any JB ever handling the keys like that, the only thing I can think of is something *designed* to prevent official updates, which, by design, happens to be in direct conflict with the 3.1/3.2 JB. Does something like that ring a bell?
