Apple released iOS 6.1.3 that effectively killed the evasi0n jailbreak. It had a good run though, lasting for nearly 6 weeks, through 2 iOS software updates, and jailbroke close to 20 million devices.
Evad3rs member pod2g has confirmed there will be no more jailbreaks for iOS 6. This means iPhone and iPad owners who would like to keep their devices jailbroken are stuck with iOS 6.1.2 until iOS 7 is released. This does not mean jailbreaking is dead like some Apple blogs are leading people to believe. Anyone who has previously jailbroken their device knows they will eventually get stuck using an older version of iOS. This is just how the process works.
