WinterBoard is one of the most popular jailbreak apps that allows you to download and install custom themes from Cydia to change the way your iOS device looks and feels. According to a recent reddit comment by Winterboard creator Jay Freeman aka saurik, the tool is is unlikely to be updated for iOS 7 due to the lack of third-party support.
Here’s the comment:
At this time, given that WinterBoard received no third-party help during all of iOS 6, I have very little hope in being able to support iOS 7. I need other people to tell me what to do to the engine: I am not a theme artist, I am just one of the few developers sympathetic to the needs of theme artists. However, I operate in a vacuum: theme artists don’t talk to me, and when they do they almost never talk about WinterBoard’s theme engine: instead, they complain about how their theme isn’t getting enough exposure in Cydia, or about some UI element. The closest was king_of_hill in April, but almost everything he wanted were complex feature requests (and the key ones were already taken care of by “use Cydget instead of WinterBoard to do what you are doing: WinterBoard isn’t designed for that”).
What I need are concrete bug reports (with screenshots and exact filenames) and core theming help (such as information on artwork files, or “car files”, at the level of the loader). If iOS 7 is even theme-able at all, and assuming WinterBoard can’t already theme parts of it, it is likely that WinterBoard will never manage to support those components as I doubt seriously that after four years theme artists will start taking the engine seriously.
To implement iOS 7’s completely new design language, it’s likely that Apple made a lot of underlying changes which break Winterboard. Saurik would not only need to iron out basic compatibility issues, but also implement ways to theme the new components introduced iOS 7 like the Control Center.
Right now you’re probably not worried much about this, since your first concern would be if there’s an iOS 7 jailbreak. But does the thought of Winterboard not working on iOS 7 concern you?
