Apple has reviewed and updated a Knowledge Base article on the potential hazards of jailbreaking iPhones, following the release on Monday of the evasi0n jailbreak for iOS 6.x. While jailbreaking is not illegal, issues with the jailbreak (and previous jailbreaks for earlier iOS versions) have been reported, and Apple is within its rights to refuse service on a jailbroken phone. Minor issues have been reported with the evasi0n jailbreak, and the article has likely been updated simply as a reminder.
