■ 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.
