Yeah those services are &quot;grey&quot; at best in many other places in the world also but are often used, I don&#x27;t think anyone is going be prosecuted for violating the DMCA for unlocking a phone unless you are running the unlocking service yourself.
That said it is a risk that some people might not want to take, but considering that people violate the DMCA by far more often by pirating various media I don&#x27;t think most people would care, or even know that it&#x27;s forbidden.
