To patch the signature checks in kernel, supply iOS 5 ipsw file to kernel_patcher.py. As up to this point, you can implement the iOS 7 interface, notifications system, both App Store & Cydia, better multitasking (App Switcher), and almost everything else that you see on Apple latest firmware. Basically, it’s a custom-built firmware that brings better interface to your old iPhone.
Many users with an old iPhone 3GS might have heard of a custom firmware called Whited00r.
