So, do you think that will Apple advertise the wallpaper that you listed as "default"? My guess is that the "default" one will be Dynamic 1.
I just called the pink one iOS 7 to call it something, and also, when I installed iOS 7 like new, the pink one, or the one that I called iOS 7 was the wallpaper that I got.
Actually Apple is advertising the Dynamic 1.
