This is no longer relevant since a different trade mark has been posted for Hail Yes. I contacted Cromulent Labs yesterday and just received a response back from them Greg Gardn Greg Gardner (Cromulent Labs) Aug 17, 09:32 MST Hi there, Hail Yes Black should work in any city where Uber operates except within China. Hope this helps. -Greg If you like Launcher, please consider writing a review in the App Store. They really help us out. Thanks! Did anyone else try contacting Cromulent Labs or is everyone satisfied posting rumors.
