Well contra has them all, until it is patched. Contra was able to get the .jar's through a program that would convert the auth into a .jar, then which he was able to crack. he has actually been working on this crack for a very long time, and impsoft will fix this crack, just as they have fixed all other cracks. Contra, and his Ex co cracker(cant remember his name atm) have cracked nexus before, and it was patched.
