Just wondering. Does anyone here have any idea how iOS 6 on the iPhone 4 is like? I know about the removal of some iOS 6 features like turn by turn navigations and things like that, But I just want to know whether there is any SIGNIFICANT performance improvements? Does the UI performance on the iPhone 4 become much more smoother? I mean, the UI performance on iOS 4 is terrible and iOS 5 fixed A LITTLE. However, the UI animations still lags alot. Especially if your home screen is full of apps: When you exit an app, it goes back to the home screen and I would usually encounter a slight stutter in terms of UI experience. What I'm wanting to know is whether the UI is much more stable and fluid. Oh yeah, when exiting big apps like huge 3D games like Fifa 12 it lags alot, in terms of the UI. To me, the UI performance means everything - it determines how smooth your device is going to be. Fyi, I'm not a developer, just a curious consumer. Any ideas? A video would be great!
