And best of all, it requires very little setup time:
I have a category on the phone now labeled, “Asshole.” It’s for spammy calls.
Which, regrettably, are on the rise. But here’s the best part:
I add them to my “asshole” category as a contact. The contact is assigned a super-special double-secret rainbow ringtone all its own: a 30-second loop of total silence. So all these jerkoffs can call and I don’t even hear it.
If producing your own ringtones, even silent ones, seems daunting, spend a little coin for any individual movement of John Cage’s 4’33”. (I’ve seen it at the iTunes Store.)
