You are suffering from a common misconception, that you can't tinker with your iOS devices. I tinker with my iOS devices all the time. As do many people, with their own devices. With help, encouragement, and software tools provided for that purpose by Apple. I just can't tinker with your iOS device.
Sure. But that's part and parcel to doing anything on there. It's not really a big deal when you can get a Mac that can do it for $300 used--it's probably going to be cheaper than the phone was.
Okay, you can install stuff for a limited time on "your own" device.
You can't use it for a non-trivial amount of time without constantly reinstall it. You can't share it with your friends. You can't make it integrate with anything else on the device.
You can tinker with it in the same sense that you have freedom of speech in a solitary confinement cell.
Oh, and only if you also paid thousands for a glorified license dongle.
