Shouldn't iPad2 have the "frosted blur" effect with iOS7?
According to AnandTech (http://www.anandtech.com/show/7343/the-ios-7-review), the blur effect requires at least iPhone 4S or iPad 4.


  On the iPhone side, the iPhone 4 lacks the cool blur effect in a number of places (notification center and control center are the most obvious), and iPad 3 does as well.
