I guess that's what made me reluctant to go there! Looks like I'd lose a lot of things unintentionally.
My aim is to erase the automatic "I've been there before" settings, but nothing else.
My choices are: Reset All Settings, Erase All Content and Settings, Reset Network Settings, Reset Keyboard Dictionary, Reset Home Screen Layout, Reset Location & Privacy.
None exactly match what the Consumer Report says, which was
"...you need to go to Reset Network settings under General settings and delete all of them at once."
My confusion was over that.
