So I noticed a very small, pointless item this morning. When you open your home screen and look at the clock it doesn't tick but moves smoothly, but if you long press an icon and make the icons wiggle, it ticks for each second.
I had not noticed the difference when in edit mode. Nice.

Just noticed that in safari, in horizontal mode, the top bar with the carrier and clock are hidden when you scroll down. It gives you a lot more viewable space now.
Only noticed this in beta 5, was it there before??
If I'm not mistaken this is just fullscreen for Safari that was introduced in iOS 6.
