Sometimes you just gotta do stuff yourself. ;)
In the PSD files, you'll find a Smart Object for 5c colors and Layer Comps for 5s colors.
There's also a Smart Object for the screen, with an iOS 7 status bar (in case you need it) and a shiny gloss layer ( should you desire that effect).
Now, I didn't name all my layers (though I name all my layer groups), but what can you expect in a freebie? :P
