Okay. So I managed to updated to 1.1.3. It is easy and all things are working... except NativeCN. NativeCN is a keyboard input software which uses UIKit. Since UIKit do not have Japanese keyboard after update, NativeCN cannot be used.
Replacing 1.1.2 UIKit to 1.1.3 doesn't work, Google Maps and Safari hangs. Any expert can help to enable the Japanese Keyboard of UIKit.framework?
