Can I remove silent mode from the volume rocker? I've got a Nexus 4.  I keep accidentally going into silent mode by hitting the volume down button.  My intention is to only put it into vibrate mode though.  Is there a way I can just get rid of silent mode from the volume rocker so that I don't do this by accident anymore?
I had the same problem. Download the app called "Vibrate mode by force" and enable the Never Silent option.

Hope it will help :)
