I understand they're both phone jacks, and I think my comment makes that clear. But I mean, the context is that USB is having yet another version, so their comment ("some technologies are already perfect") seemed to be that the original 1887 jack is precisely the same revision of the phone jack he doesn't want removed from his mobile phone. I hadn't actually thought of the two meanings of "phone" in my comment, I understood that "phone jack" refers to telephone switch boards. I just assumed they were talking about removal from mobile phones because that's where those jacks are notoriously being removed.
