Well, this is the real problem here. At this moment, there is no publicly released Jailbreak iOS 13 application. So it is not possible to download Cydia on iPhone 11 at the moment. However, if you are not focusing on Cydia Download for iPhone 11 using a Jailbreak iOS 13 IPA file, there is a way to download Cydia iOS 13. And that is called semi-jailbreaking. In semi-jailbreaking, you don’t have to download jailbreak IPA files to install Cydia on iDevices. It uses a simple partial jailbreak procedure to directly install Cydia on iDevices. All you have to do to download Cydia using a semi-jailbreak tool is, visit the official website of the tool and click on the download button.
