Automaton: iPhone UI Kit - MediaLoot
Here is a cool UI kit designed with the iPhone 4 and it’s Retina display in mind, this set covers all the common UI elements, and is ready to use right out of the package, ideal for UI design and wireframing iPhone apps.
Of course, with a little tweaking this set could also be used iPad apps or other platforms such as Android and Windows phones.
Included in the package are two PSD files, one for the Retina resolution and one for standard (pre iPhone 4) resolution.
