Flat iPhone 5 Black & White PSD is a free Mockup design resource made by Dribbble user Nick. 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.
