This last sentence, from the article, indicates that this ruling is actually a step backward:
"On EFF's request, the Librarian of Congress renewed a 2006 rule exempting cell phone unlocking so handsets can be used with other telecommunications carriers. Cell phone unlockers have been successfully sued under the DMCA, even though there is no copyright infringement involved in the unlocking. Digital locks on cell phones make it harder to resell, reuse, or recycle the handset, prompting EFF to ask for renewal of this rule on behalf of our clients, The Wireless Alliance, ReCellular and Flipswap. However, the 2009 rule has been modified so that it only applies to used mobile phones, not new ones."
