> I am not allowed to do projects that allow me to gain the skills I would need to build this tech in Germany

Can you give examples of what you must be able to do to learn this, but isn't allowed to "do" and that doesn't have any other alternatives to learn?

The creation of tools to circumvent security measures that protect “data”, is punishable by up to 2 years in prison under vague conditions here.

So anything that would build skills towards being able to crack an iPhone is at least legally ambiguous.
