I suspect you're correct about it being 2 and 3. I've never had a failed iPhone, iPad, or MacBook power adapter that was apple manufactured. My wife on the other hand goes through about one phone charger every 6 months. Absolute disregard for how the cable is positioned (like if the cable is being crushed or snagged by an object). I guess growing up with those brittle NES controller cords taught me something.
