BlackBerry might be teaming up with Amazon to add its App Store to BB10 but they will also be shutting down one of its services soon. BlackBerry announced it will shut down its BlackBerry World Music and Video services on July 21st. Those who have bought and downloaded content from the service will still be able to access their content after July 21 through MyWorld. Since the company is opening its doors to Amazon, they believe his will give users access to third-party music and video services.
