I wish to set my calls as ringtones (which they are now, ringing fine) and my texts to vibrate. Right now, I can't seem to set it for this combination. I can either set it for ALL VIBRATE or ALL RING. I do not wish to do either of those options. Currently, my calls are all set up to ring, I just want my texts to vibrate in this same sound profile. Am I doing something wrong or is this option just not available???
