From the almost complete iOS 1 la iOS 7, the HomeScreen of iDevices has gone through various changes, but none are as radical as this year's. If you look carefully you will notice that in the first 3 versions of iOS new applications were added and nothing more, in iOS 4 the resolution was increased and some new applications plus a wallpaper were added, in iOS 5 only new applications appeared, in iOS 6 the resolution increased , the wallpaper changed again and new applications appeared, but in iOS 7 the interface was completely changed.
If we look at the evolution of iOS based on these images, we could say that iOS 7 it's the biggest change since iOS 1.
