Simple,online, and free

This tool generates iPhone/iPod icon from any image. Glossy & corner rounding effect are

applied so icon will look exactly like on iPhone/iPod.

GIF, PNG, JPG, BMP, TIF etc. formats are supported (with alpha-channels too)

Image should not be smaller than 57×57 (larger images will be scaled and cropped automatically)

It works like a charm much props to the creator.
