Hey, I've had my iPhone 4 16gb for about a week now and I'm loving it. It's just that the interface isn't as smooth as I'd like it to be. For e.g. when I unlock from the lock screen to the first page of icons the animation is a little jerky (low FPS). Or when I use the double-tap home button for multitasking, then tap back to home screen it stutters a bit aswell. When I repeat the process, the next attempts seem smoother. It's like the phone needs to "load the process" before it starts doing it smoothly. Is anyone else experiencing this? Should I restore the firmware? I haven't touched it on my new iP4 yet. Thanks for your replies in advance!
