What I want even more at this point (and have told Apple as much) is a way to even prevent the phone from ringing. Yes, Airplane Mode and other hacks can do it but I want something better and OS-supported.<p>Maybe “making calls” was the killer app in 2007 when the iPhone was released but these days the idea of the ENTIRE DISPLAY being <i>taken over at random</i> is too much. I am almost certainly browsing the web or using some app and the timing is always <i>terrible</i>, shoving some unknown number in my face.<p>And yes, telemarketers are probably 95% of calls at this point. A huge number of people just text me or use something else. And even if you must call, leave a voice mail (which telemarketers never do).
