Ok, I know this will seem like a really stupid question for some, but I've got less than 24 hours experience with jailbroken iPhones. So, I got it jailbroke, no problems. Once done, I now have Cydia, and Winterboard. Through some screwing around, I've figured out that Winterboard is used to load new themes. (?) I've downloaded a few different themes. Some work, some don't. So that leaves me wondering, are some themes not compatible with Winterboard? If so, what else do I need? Is there any way to search themes that are only Winterboard?
Sorry if this is a dumb question, but my meager searches aren't yielding me answers.
