Another question, i came across a page to inform me to be a "VIP" where there is cloud save, more friend invite and such. I accepted and it sort of link to Facebook. I went to my iPhone setting and iCloud. Didn't see any saved file or such. Is the iCloud save rolled out or not? I also can't find any button to upload the current progress to the game. So is the game tied to Facebook or iCloud or both or? It's confusing. So can I safety delete this game and reinstall and get back the same progress? Or does backing this up to iTunes Save the progress. Going change to iPhone 6 soon, so I really need to know how to backup this. Please advice many thanks.
