Unlocking cellphone from carrier will become illegal on Jan 26th in U.S?

I just heard on lockergnome on Youtube that unlocking your phone that you got from your carrier will be illegal, has anyone else heard something similar or can confirm it? Why hasn't the Verge reported on it? Does it mean that you won't be able to bring your old Samsung Galaxy or HTC from Att to MVNOs like Straight Talk or SIMPLE?
