I recently had the need to use a nice clean image of a smartphone. I began searching through the numerous images found via Google and eventually came across this freely available layered Photoshop file of a BlackBerry – just what I was looking for from a user over at DeviantArt. 
The 6.2 MB download expands to a 15 MB PSD image containing, well, a ton of layers – allowing you to customize the heck out of it.
