The iPhone can store up to six pages of application icons on the home screen, and thanks to the new operating system you can group similar applications by specific categories to free up more space on your home screen. Categories such as business, lifestyle and communication store up to nine applications and open a sub-menu when you tap the category icon on the iPhone's screen. The iPhone allows you to re-arrange your icons in iTunes when the iPhone is connected via USB connection, and synchronizes the new categories in iTunes and the iPhone.
