The distribution of the "leaked" update is basically IP theft. It has nothing to do with hacking your phone to do something it otherwise couldn't do, like an iPhone... which is basically crippled to the point of only being able to do what Apple wants it to do out of the box.

Copyright laws suck and need to be totally revamped.
