Terrence pointed out to me that the latest leaks (6.0.0.337) for the BlackBerry Torch 9800 and even one official release have shipped with Facebook v1.8.0.51. I noticed the same thing when going to App World and it shows the message to the right.
Facebook v1.9 is already in BlackBerry Beta Zone so I don’t think there are any crazy new features but I thought I would mention the update. Nothing really crazy in this latest build but if you want to check out the java files for yourself you can find them at these links:
