I use iPhone 4 with iOS 6 and apart from the app store (which I guess is slow everywhere, looking like being implemented in HTML 5 and stressing servers) nothing is slower than before iOS 6.

My camera takes about 6 seconds to launch compared to being near instant before iOS 6.

I've just tried, I get about 6 seconds only if I used a lot other things, but still near instant if I've used the camera recently.
