I spotted two new features. Firstly, there is the new multitasking UI. In older version, you can see the icons of the running apps. This version you can see the screen shots by pressing menu button. And then just press the screen shot, you can switch the apps.Well, that is in android world for long time.....

The second one is a bit annoying. It will authenticate the connection cable. It will reject all non-authorized cable. My one is non-apple one, I cannot use it to charge my ipad anymore/
