Having 11 pages means you will be able to install 180 applications on your sweet iPhone up from 150. It might be a nice feature for those without jailbreaking iPhone, as the jailbroken iPhone owners don’t need that much pages. They can manage their apps in categories.
More Pages means more Apps. and for more Apps you need a speedy iPhone i.e: iPhone 3GS
