The Electronic Frontier Foundation (or EFF) is once again fighting to keep the practice of jailbreaking legal. The non-profit digital rights group announced this week that it has filed a petition with the Librarian of Congress and the Copyright Office to extend and expand the exemption that allows you to jailbreak your phone, without violating the Digital Millennium Copyright Act (DMCA).
Because the software on mobile phones and tablets is copyrighted, the act of jailbreaking (and rooting on Android devices) is technically forbidden by the DMCA. But Congress created a procedure to allow for exemptions on activities where users make fair use of copyrighted works, reviewed every three years. The last exemption for jailbreaking was awarded in 2012, so it's set to expire soon.
