Digital rights management
Digital rights management (DRM) is copyright protection, designed to
prevent modification and to limit distribution of protected files. When
you download protected files, such as sound, video, themes, or ringing
tones to your phone, the files are free, but locked. You pay for the key to
activate the file, and the activation key is automatically sent to your
phone when you download the file.
To view the permissions for a protected file, scroll to the file, and select
Options > Activation keys . For example, you can see how many times
you can view a video or how many days you have left for listening to a
song.
To extend the permissions for a file, select Options and the
corresponding option for the file type, such as Activate theme . You can
send certain types of protected files to your friends, and they can buy
their own activation keys.
This phone supports OMA DRM 1.0.

your phone.
Warning: If you install a software update, you cannot use the
device, even to make emergency calls, until the update is
completed and the device is restarted. Be sure to back up data
before accepting a software update.
