If your device has OMA DRM protected content, to back up the content, use the
backup feature of Nokia PC Suite.
If your device has WMDRM protected content, both the activation keys and
the content will be lost if the device memory is formatted. You may also lose
the activation keys and the content in case the files on your device get corrupted.
Losing the activation keys or the content may limit your ability to use the same
content on your device again. For more information, contact your service provider.
