Custom icons worked on 3.10 now for a few weeks since the topplugin was decrypted. Just get the generic rco editor by zinga burger or use an icon set made for 3.10 if you dont want to create your own. If you use an icon set you can just flash it through the flash access in your recovery menu.
I actually just downgraded to 3.03oe-c, ran XMB Flasher 0.2 but it did nothing. Damn, I am having enough trouble just to change my XMB to Gears of War.
