I for one have been looking forward to an update to WinterBoard since I first got my iPhone. Being a theme designer as well, this makes me super excited, and it should for all you theme lovers as well!
For those of you who might not know, WinterBoard is an App developed by @Saurik
that allows Jailbroken users to completely change the look and feel of their iDevice. Through Icons, Sounds and User Interface redesigns.
