failbreak

The term failbreak stands for a jailbreak that cannot be released, so it's some kind of a fail. This term came into discussion when chpwn showed a screenshot of his new iPhone 5 running Cydia shortly after its launch on 19 September 2012. A little later, this term became common and on 19 October 2012 even planetbeing twittered that he upgraded the failbreak with a kernel exploit so that tweaks actually work on the iPhone 5, "almost a full tethered jailbreak".

The problem is that it requires an Apple developer account and developers are under an NDA.
