About organizing application icons
Application icons can appear on the Home screen or in folders on the Home screen. If you cannot see all your application icons, they might be hidden. You can make all your application icons visible on the Home screen or in folders by selecting Show All from the Home screen menu.
You can reorder application icons to change which icons appear first on the Home screen. You can also create and delete folders, change the folder icon style for folders that you create, and move application icons into folders and out of folders.
