Saurik now offers Cydia 1.1.9 for jailbroken devices. The shop to install tweaks and other themes of all kinds now adapts to iOS 7. In theory, this version should have seen the light at the output of the jailbreak, last Sunday, but several factors have delayed it, main one, is that hackers have not notified Saurik.
This version is quite nice and fits perfectly in iOS 7. The interface has been redesigned to certain levels, the keyboard of iOS 7 is integrated. In short, this update is available on all jailbroken devices. Note the absense of a new Cydia icon on the home screen.
To get it, just open Cydia and accept the updates at startup. Cydia will then install them and ask the user to exit the application. At the reopening, the new theme will be applied.
