I'm new to the iPhone, but not new to Apple products otherwise. I just got a 4s, and I can't find a way to switch email, fb, etc to vibrate only while keeping the ringtone in audible mode. In fact, I never want to HEAR an email notification. I can't believe that is even the default. I've seen some rather complicated work arounds, but having to do that seems very.. non-Apple. Wouldn't they have some sort of intuitive buttonless trick? Not trying to stir things up, just trying not to be annoying. I hate devices that make unwarranted sounds.
