Cody Sanfilippo is so distraught by iOS 7’s design that he offers up his own PSD to Apple. This is it.
A PSD for you, Apple. Please take it. is a free PSD design resource made by Dribbble user Cody Sanfilippo. As far as I can tell, its license is Unknown.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
