Facebook for BlackBerry smartphones has been updated to version 3.3. According to the change log on Inside BlackBerry, this version has slightly been redesigned with “refreshed” icons, plus gives you the ability to search and add BBM friends, and initiate BBM chats within the Facebook app. There’s also a new look to the how you can view your photos, now in higher-res and thumbnail view mode. In addition, if it’s your thing, you can now un-friend easier.
This should be hitting your device now, or will be within the next 24-hours.
