So North Korea apparently has an android phone with basically a rootkit on it, that doesn’t allow you to open anything not signed by it on it, takes screenshots periodically and stuff.
Now assume you just wanna get around this, and have tools available, how do you do it?
Would you need to solder a new memory there? Could you try some sort of exploit first?
I think the solution will be a separate device. Even if you tampered with the one you’re given, you’re still running on their network. Even if you wanted to just chat over Bluetooth mesh with your fellow Winston Smiths, this doesn’t seem like a good idea.
In the border regions with China, some people who want to communicate with the real world, have phones that connect to the Chinese networks. A satellite able device would be better but probably too expensive.
