Freebbble!

Designed for the base Retina iPhone icons (120×120px).

iOS 7 Base Roundrect Shape / Icon Template is a free Template design resource made by Dribbble user Ricky Romero. 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.
