Freebbble!

…well, the mug is a nice touch. After Effect file.

iPhone 5 Presentation Template with Mug is a free Various design resource made by Dribbble user Chris Slowik. 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.
