How often do you redo your iPhone or iPad ?
What exactly do you mean by redo? Do the "Erase all content and settings" and just start fresh?
I've never tried that, although I love setting up a new iPad / iPhone instead of restoring from a backup. Feels good.
NEVER. Though when El Capitan dropped, I decided to do a fresh install, and restore my documents from Time Machine. Does that count?
