ok... i have installed the installer app on my iphone, and have since installed the latest version of summerboard.  It is working properly, except that I basically have 2 different backgrounds.  One is my wallpaper on the lcok screen, and the other is my background from using iFuntastic 3.0.3.  I have tried making both the same, but that doesnt really work.  Also, the square space around the icons are different colors, pictures, etc.  Can someone please give me a runthrough of how to make one cohesive background and not have the icons look like they were crudely pasted on. 
I am using an ibook g4 ppc, along with iFuntastic, cyberduck, and the installer app. 

Thanks

Also, could someone please instruct me on how to install themes using these programs?
