I do not have an iOS device yet, just looking for how things work. Let's say I want the phone sound notifications for only calls (or normal ringing) and text messages. I don't want email, espn, Facebook, etc notifications making sounds, but I do want to see them on the notifications area. Is there an easy way to do this? And how easy is it to toggle between that and having all notifications make sounds? It would be ideal if I could configure do not disturb to allow phone calls and a list of apps I specify (like messaging).
