Yeah resetting settings or something else or tweaking DND settings doesn't really solve the issue. Calls do come trough fine for the most part and sometimes it might seem like some change you made fixed it, until sooner or later a call won't come through once again.Resetting network settings (Verizon 4S) and changing DND to everyone did not resolve this issue for me. Although beta 2 isn't as snappy and the camera crashes more often it seems to be working just fine. I can live with these minor nuisances compared to missing important phone calls. Im just hoping enough light is shed so that it can be fixed for beta 4
