Facebook 3.1 brings a couple of key improvements to RIM's platform including support for Facebook Groups. Facebook Groups have quickly become one of the most used features of Facebook and its great news that you can now keep up to date and communicate with your groups on your Blackberry smartphone.
Additionally, Facebook 3.1 now enables users to "Like" individual comments from inside the Facebook App on their Blackberry device. This feature is also widely used and we're surprised it wasn't included in previous versions.
The previous version of Facebook Blackberry became "BBM Connected". Being BBM Connected means that the application incorporates BBM functionality inside the application, which enables users to chat on BBM at the same time as browsing on Facebook.
