I can’t find the old settings icon in iOS 7. Does anyone know where it is?
I don't understand your question either, but if you're referring to changing an icon then that's not possible. If you're referring to the Settings app, well that's still there and it looks somewhat similar (except it looks more like a gas burner now).
You can't delete it, so if you've lost it there's a good chance it's hiding in a folder somewhere :)
What do you mean by "old settings icon"?
The settings icon has been changed. You can see the new icon in this photo
