Every time I go into the Apple store they ask me how much I like my iPhone 7 Plus 256Gb, and can't help but tell them I am totally dissatisfied that I can not administer my device like I can with my Android devices. Google allows you to unlock their bootloader and I am running Resurrection Remix on a Nexus 7 2013 with so many tweaks and options that would make Cydia cry. They think if they allowed this for the iPhone it would make it weak and unsecured as well as people downloading applications that have to be paid for and get around that and instal them for free. I may have done this with one or two apps in the past but its not worth it, they never work correctly, since then I have paid for all my applications as well as Cydia apps. Its too bad Apple cannot design it so you could root it but somehow make it so the user cannot use apps for free that you must pay for.
