Customizing the Home screen
For more convenience using your phone, add your favorite apps, widgets, and downloads to the Home screen for quick access. You can also change the wallpaper to reflect your personal style.
TIP!
From the Home screen, tap the Menu
key 
, tap Home screen settings, then checkmark Portrait
view only to keep the Home screen from rotating to landscape
view. This is a separate setting from the Auto-rotate screen setting that applies to the rest of the screens.
