iPhone 5 Grid
Don’t forget to check the Dribbble post for more details, including this freebie grid for iPhone 4.
iPhone 5 Grid is a free design resource made by Dribbble user Eddie Lobanovskiy. 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.
