my question's are simple i believe, can you change the home screen background without theming it? for now im happy with the standard button's

I've unlocked it using ibrickr and jailbird, i just want to put the mac clownfish on the home-screen background instead of black.

in case i do have to theme it, i made a ipb of whatever using the link above for the online skinner, and saved it. did i have to put icon's in there 2? or can i leave them bank and just put the background on there?

what's my next step? if its already been said and done, just link me and ill pick it up from there.

thanks in advance
