We all want an update, Black Glass is the best thing going out there! But I learned early not to rush the developers... they all do their best and get their stuff out to us when they can. Thanks Dave!
There were a couple other themes for 4.7 that were able to load up okay by simply removing the settings.apk from the theme. Not sure if BlackGlass would work the same way, it may save you from having to wait on the phone.
