I just got finished completely customizing my SummerBoard with my own theme and (mostly) all custom icons.
A few of the icons are default/used from other themes, and all others are from deviantArt.
Edit: Download This Theme Now!
If something in here is your own work (and you can prove it) and you would like it removed or you want to be credited, I would be more than happy to do so. Please PM me. And the mandatory disclaimer: I didn't make any of these icons, I just edited them to fit on the Touch. They are all owned by their original creators.
The theme only has icons for the apps you see in the screenshots above. If you want me to try and make/find an icon for another app that isn't listed here, reply and I'll see what I can do.
