I want to submit a package that has multiple WinterBoard themes, but the last time I did that they put all the themes in one folder with the extension ".theme" and therefore when you activated it it did nothing.
Multiple things to activate in winterboard? If this is the case, I package themes at the root level...
Library/Themes/whatever.theme for each works like a charm
Then you just have to zip up the library folder and submit it to the dev portal, hope this helps
