iOS and Android both have something called FOLDERS where you can group like-minded apps together, to decrease the clutter. Touch the folder, it bubbles out to show the contents. I use them to decrease the icons on the home page and to keep the number of pages I have to scroll through to, basically, one.
Your comments about your dislike for iOS on the iPhone is rather odd, though, because if you read it, the same issues you describe are exactly what I would describe your own WP screens (cluttered and having multiple pages to have to scroll through).
