This is exactly what jailbreaking fixes. By default, iOS does not allow you to install apps that are not published in the App Store.

Well, unfortunately jailbreaking "fixes" the problem by ruining code signing integrity on the device. Ideally, the jailbreaks would leave code signing enforcement in effect but just augment the default trusted CAs/CDHashes. I'm disappointed that AOSP never gained the code signing framework that iOS has, allowing people to have better Freedom and Security simultaneously.

Well, you can't update an app with the same app signed with another certificate.
