OMA 1.0 and OMA 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 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.
To view the digital rights activation keys stored in your
device, press , and select
