I really liked iPhoneyAdium by Alexander Weiss [link]
but I wanted a blue version to match the other icons in my dock so I decided to create one and here it is. The original icon was 128x128 pixels and green, so I redrew it at 512x512 pixels and changed the color to blue. Thank you to Alexander, he kindly granted me permission to submit this.
There are two versions included:
1. PNG format at 128x128. When I had the .png files at 512x512, it caused jagged edges in the dock.
2. ICNS format at 512x512. The .icns files resized smoother in the dock.
