Pre-orders and previews underway ahead of launch.
'Evasi0n' Untethered Jailbreak Updated for Newer iPhones, iPads and iOS 7.x [Updated]
However, Cydia administrator Jay Freeman noted on his Twitter that he was not informed about a new version of Evasi0n before its release, also indicating that the build of Cydia installed with the new jailbreak is not official and may lead to some compatibility issues with existing downloads on the service. However, users on our forums are actively pointing out which Cydia apps are compatible with the new jailbreak, and it is recommended you look there for specific information.
Evasi0n is available now for OS X and Windows as an untethered jailbreak, with users only having to apply the method once. Tethered jailbreaks requires users to have their devices connected to a computer each time they restart.
Update: Cydia administrator Jay Freeman has also revealed on his Twitter that Evasi0n installs a third party "app store" named Taig for cracked apps in China. Furthermore, two tweets by developer i0n1c (via Y Combinator) state that a Chinese company paid the Evad3rs development team a rumored $1 million dollars to release the jailbreak in order to force the Taig app store onto devices.
