This isn't a full project.
it's an AE 3D (duplicated layers) iPhone 3 and iPhone 4. i use it a lot in many of my projects.
The iPhone, the shadows and the reflection are all separate objects and as such they are easy to manipulate. the iPhone screen is procedural, which means that everything you change in the screen comp will show in the main iPhone comp on the iPhone and it's reflection.
it renders very fast - so have fun with it and leave a comment or a link if you do anything cool with it.
