I've only recently had iPhones that come with a model-specific wallpaper by default. Before that, every iPhone or iPad I've ever had has come with whatever wallpaper was the stock wallpaper for that version of iOS. If I was to do a wipe, or even a DFU restore of an iPhone or iPad that had one of those model-specific wallpapers, does it come back as the default? If not the default, is it there to select? I'm curious.
