Iphone icons for a simple application

I am about to publish a new application that allows to list and organize a collection of items. The application is targeted to coin collectors, stamps collectors etc. but the program is generic, not stricly related to coins and stamps. I need you to create an evocative icon for iPhone and for Mac OS X. I also need a splash screen for both iPhone and Mac OS X. You should be familiar with Mac OS X and iPhone. Technical details: - iPhone splashscreen: 320x480 px, PNG + InDesign or PSD - iPhone Icon: 57x57px, PNG + InDesign or PSD - iPhone Big Icon: 512x512px, PNG + InDesign or PSD Moreover i need a refresh icon (classic two arrows imgae, black and white, 1 bit with alpha channel, 40x40px) and a simple icon to simbolize items that you may collect (full color, png, 40x 40px).
