The Life, Death, and Legacy of iPhone Jailbreaking (vice.com)
From a Motherboard article: Jailbreaking is the art of hacking into Apple's ultra-secure iOS operating system and unlocking it -- and thus allowing users to customize the phone, and write or install any software unimpeded by Apple's restrictions. At the time I met with Todesco (a person who offered jailbreaking service), in December 2016, there was no known jailbreak (for the iPhone 7) -- no public knowledge of this hack -- for the latest iOS version that was installed on my iPhone (iOS 10.2). The world's first jailbreaking step-by-step procedure, discovered in 2007, was posted online for all to see. Subsequent jailbreaks were used by millions of people. At one point, there was even a website -- called jailbreakme.com -- that was free for all to use and jailbroke your phone simply by visiting it. [...] Ten years after the iPhone hit the sleek tables of Apple Stores worldwide, and the first-ever jailbreak, that Wild West is gone. There's now a professionalized, multi-million dollar industry of iPhone security research. It's a world where jailbreaking itself -- at least jailbreaking as we've come to know it -- might be over.
He also left out the part where the dev kit costs $100/year and that you need at least a $1500 Mac to run it on. So, sure, "anyone" can do that, at long as they're OK with paying out the nose for the "privilege".
You don't need to pay the $99/year anymore actually. They made it free a couple of years ago if you aren't going to be selling anything through the app store. You still need access to a mac to compile it and load it onto your iphone though.
You left out the part where you need electricity to power everything, a place to house the stuff. Oh, and sustenance and oxygen to breath.
BTW, for personal use the dev account is free to use and deploy to iOS devices. I know it's hard to keep up with 2 year old news but please do try.
Apart from the fact Samsung don't own the Google Play store.
And the even bigger fact you can install anything you want on your Android from any store you like, or even no store at all.
