Research in Motion (RIMM) recently updated its BlackBerry Messenger application to include free Wi-Fi calling. With the release of BlackBerry 10 just around the corner, RIM is looking to add even more features to its flagship messaging app. Slides from a purported internal BlackBerry 10 presentation that were originally posted on the CrackBerry forums suggest that the company is planning to update BBM to include video calling and screen-sharing capabilities. A second slide highlights a task manager application called BlackBerry Remember, which is believed to be the replacement for RIM’s native Tasks app. Additional slides from the presentation can be viewed below.
