Unlocking Cellphones Becomes Illegal in the U.S.

The clock to unlock a new mobile phone is running out.

In October 2012, the Librarian of Congress, who determines exemptions to a strict anti-hacking law called the Digital Millennium Copyright Act (DMCA), decided that unlocking cellphones would no longer be allowed. But the librarian provided a 90-day window during which people could still buy a phone and unlock it. That window closes on Jan. 26.
