Facebook, the worlds biggest social networking site, has updated their Mobile app. Now you would think being so close to the release of the iPhone 4 and iOS 4 they would update it for that, I guess not yet. Updates in Facebook 3.1.3: You can now watch Facebook videos. You can now view and write on walls of events. Uploaded photos are now 720px wide. Bug-fixes: Could not comment on photos accessed from Notifications Could not upload photos smaller than a certain size No more than 2 notifications were highlighted as unread Status updates appeared out of order in News Feed Broken photo album links in News Feed Birthdays view had months in wrong order Last section of friend list was incomplete if you had fewer than 8 friends Notes with non-ASCII text were cut off at the end I actually feel sorry for everyone who reported the bug claiming they have less than 8 friends.
