In addition to jailbreaking, other exemptions announced Monday would:
• allow owners of used cell phones to break access controls on their phones in order to switch wireless carriers.
• allow people to break technical protections on video games to investigate or correct security flaws.
• allow college professors, film students and documentary filmmakers to break copy-protection measures on DVDs so they can embed clips for educational purposes, criticism, commentary and noncommercial videos.
• allow computer owners to bypass the need for external security devices called dongles if the dongle no longer works and cannot be replaced.
• allow blind people to break locks on electronic books so that they can use them with read-aloud software and similar aides.
Although the jailbreaking exemption is new, all the others are similar to the last set of exemptions, which were announced in November 2006. The new rules take effect Tuesday and are expected to last a few years.
