ok i think i stumbled onto an easy way to upload themes. using fugu i connected to my iPhone. once in you should be in the root file, click on library. once in library go down to the summerboard file and click into that. once in there there should only be a theme file. all i did was copied the "louie matia" file and replaced all the .png files with my own. after that you just drag and drop the file into the themes file. if you want better details just send me a message on here.
