You can change the normal wallpaper used on the telephone's home screen. This enables you to customise it to match your company's corporate design or your own preferences.
There are the following ways to change the home screen:
•Provisioning
−Provide the image in the form of a Base64 string
−Provide a link to an image file on a web server
•Set an image in the Android Gallery as the wallpaper for the home screen
•Set an image from a USB mass storage device as the background for the start screen
Note: The image remains on the phone even after removing the USB mass storage device.
If an image does not have the set dimensions, it is scaled and trimmed.
