From the bizarro retcon article of the day, I surfed to the article on Library of Congress ruling iPhone jailbreaking legal. Look what was buried in the last paragraph:

"In addition to this decision, the Library of Congress also granted an exception to artists who remix copy-protected video content for noncommercial work, and renewed its approval for cellphone owners to “unlock” their phones or lift controls that restrict use to one wireless carrier."
