Apple also told regulators that the nation’s cellphone networks could suffer “potentially catastrophic” cyberattacks by iPhone-wielding hackers at home and abroad (.pdf) if iPhone owners are permitted to legally jailbreak their shiny wireless devices.
Apple spokeswoman Natalie Kerris said Apple won’t change its policy that voids iPhone warranties if a phone has been jailbroken. “It can violate the warranty and cause the iPhone to become unstable and not work reliably,” she said.
Apple is pretty much implying that the dislike the use of jailbreaking an iDevice. I guess if you do not download copyrighted tender from installous, you are ok.
The jailbreaking exemption was part of a handful of exemptions announced Monday, including:
• 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, documentary filmmakers and producers of noncommercial videos to break copy-protection measures on DVDs so they can embed clips for educational purposes, criticism or commentary.
• 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.
