If you’re jailbroken on iOS 10 and yearn to make your device look like it's running iOS 11, then you’re in luck because prominent developers are taking on a full-scale project to bring several iOS 11 features to the jailbreak community before the operating system update is released this Fall.
The project is being undertaken by iOS developers LaughingQuoll and Antique_Dev, and will be called Eleven. It will be a collection of multiple different jailbreak tweaks that each focus on specialized features of iOS.
