This thread will have homebrew icons for your apps. To use them, download the image, and rename it to icon.png. Then, go to the folder of the app in your SD card (where boot.dol is) and paste the icon in the folder. If you already have one, you can overwrite it. You can also request icons in the reply section
Note: I don't have many icons, since I'm still busy making 'em
