■ Digital rights management
Content owners may use different types of digital rights management (DRM) technologies
to protect their intellectual property, including copyrights. This device uses various types of
DRM software to access DRM-protected content. With this device you can access content
protected with WMDRM 10 and OMA DRM 2.0. If certain DRM software fails to protect the
content, content owners may ask that such DRM software's ability to access new DRM-
protected content be revoked. Revocation may also prevent renewal of such DRM-protected
content already in your device. Revocation of such DRM software does not affect the use of
content protected with other types of DRM or the use of non-DRM-protected content.
Digital rights management (DRM) protected content comes with an associated activation
key that defines your rights to use the content. 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 AT&T. Some
activation keys may be connected to a specific SIM card, and the protected content can be
accessed only if the SIM card is inserted in the device.
If your device has OMA DRM-protected content, to back up both the activation keys and the
content, use the backup feature of Nokia PC Suite. Other transfer methods may not transfer
the activation keys which need to be restored with the content for you to be able to
continue the use of OMA DRM-protected content after the device memory is formatted. You
may also need to restore the activation keys in case the files on your device get corrupted.
