I used to cover my 3GS with an otterbox but when I got my 4s I said "no way". Why take a slim phone and turn it into a big, ugly hunk of plastic? I have a visor shield on the front of my 4s and clear, thin shield on sides and back. You can't tell there's anything at all on my iPhone! And guess what? I've dropped it MANY times and it's in one piece still. It's insured for a reason and it still fits in my pocket
