We've been waiting on this for a couple weeks now and the White House has finally come through with its response to the cell phone unlock petition. The short version, for the tl;dr crowd is simple: "The White House agrees." Citing not just smartphones but tablets as well, the Executive branch of the U.S. government states, in no uncertain terms, that there should be no reason that carriers should block a customer from switching carriers once contractual obligations are fulfilled.
In October of 2012, the Library of Congress elected not to renew DMCA exemptions that explicitly allow end users to unlock their cell phones at will, thus ending a six year tradition. This has made a lot of people very angry and has been widely regarded as a bad move. The quest to do something about it began almost immediately. And by "almost immediately" I mean "nearly three months later and at almost the very last minute."
Still, regardless of when the outrage gained steam, the fact is it did.
