When I had a blackberry, I could set my ringer off, and it would silence all incoming calls but I could set some contacts so that they would still ring. Any apps for the iPhone that can silence all calls except for certain contacts?
It's a long work around but basically I just made my own silent ringtone and set it to default and gave people who I don't wanna miss calls from a custom ringtone. Badda bing badda boom
