I meant I want to side load apps on my phone that I don't write that other people make that perhaps violate Apple's rules. Like one that replaces springboard for example. Without having to jailbreak.
I agree. I would like to see something like we see with Linux distros. Whether I'm using apt, yum or dnf I can add a third-party repo for my package manager to download and install from. When I was into jailbreaking my phone that is what this basically meant to me even though I had to go with a different package manager (I think it was called cydia).
