That's because the Librarian of Congress, given permission under the law to make exemptions to the DMCA, had determined that the U.S. cell phone market benefited from the ability to unlock phones — but that's now changing, as the librarian's office believes that there are now enough unlocked phones available for purchase that users don't need to hack their own phones. Starting this Saturday, unlocking a phone that was locked to start with will be illegal." Link to Original Source
