This case study looks at "jailbreakers," who are hacking their iPhones so that they may use unauthorized software and applications from other cell phone carriers. Apple has warned that such hacking will not only damage their iPhone, but is indeed copyright infringement. However, the Copyright Office has actually proposed that "jailbreaking" is actually considered "fair use." In the past, other laws, like the Sonny Bono Copyright Term Extension Act (1998), have been used to protect creative property for much longer than actually necessary, thus diminishing valuable work available in the public domain.
