A Right to Unlock Cellphones Fades Away; New York Times, 1/25/13

Brian X. Chen, New York Times; A Right to Unlock Cellphones Fades Away: "Your right to unlock your cellphone is about to expire. Cellphone carriers say this is for your own good — and theirs. Unlocking a cellphone enables it to work on a wireless carrier other than the one you bought it from. If an AT&T iPhone were unlocked, for example, it could be used on T-Mobile USA’s network. In October, the Library of Congress decided to invalidate a copyright exemption for unlocking cellphones. This exemption expires Saturday, making the act of unlocking a cellphone potentially illegal, unless it is authorized by a carrier."
