Hi, this sounds really amazing and I’m looking forward to use your tool soon.
I have a question though, what about the on-screen text? As I can see on your images, the localization of your device’s text is english. Doesn’t that possibly confuse a potential non-english speaking customer? I’m not sure how many app-store visitors actually are aware of the “available languages” section on the app-store app’s details page. But still, this tool handles lots of work. Thanks for developing it! :)
