With this [Check Attachment] I can confirm that Turbo chips not working with iPhone 5s 7.1.2 ARE WORKING for iOS 8 GM. If you are on turbo sim for version 7.0.6 or below. You can update to iOS 8 and still use your turbo sim. This is the best pic to show that it works I couldn't take any other screenshot. Screenshot taken on iPhone 5s - 8.0 (12a365) - R-Sim 9 Pro.
