I think apple will the officially launch IOS7 final version very soon. I see the interface is quite nice. I have been using Iphone from Iphone3. I think the UI of IOS 7 is the best one. However, I am concerning about its stability, But, anyway, I am really to be the first one to try it. 🙂
Will you try?
