Yes, it’s entirely possible to use the Contra code to unlock your iPhone, though the controller lacks a Start (or Select) button. Have a look at our video walkthrough inside…
After you install Control Unlocker on your iPhone, go to the tweak settings menu where you will be able to create your own unlock style and over there you will find a kill switch for the tweak, and a setting for establishing custom text to brand the controller.
Although Control Unlocker works with a passcode, it won’t outright replace a passcode if you have one set. This means that every time you input the correct button combination, the passcode prompt still pops up next. You can outright bypass Control Unlocker using a pinch gesture on the controller, and jump right to the passcode, but that kind of defeats the purpose.
Control Unlocker was scheduled to be set at $0.99, but the developer, Stevie Hetelekides, has since decided to make the tweak free of charge. You can find it right now on Cydia’s BigBoss repo. Let me know what you think about it down below.
