> The non-technical iOS users I know would never change a setting in Settings they do not understand

I wish I had your circle of non-technical folks. I've been called (from other people's phones, no less) numerous times asking why data doesn't work (they deleted all the APNs from an Android phone), why their picture messages don't go through (they changed the MMSC URL to their homepage), why voicemails stopped (they set the voicemail service number to their own number), and several more. Changeable settings are like mountains; they're messed with because they are there.
