Facebook has released an update to its popular iPhone application adding the ability to view Facebook videos through the app. Previous versions allowed users to upload video to Facebook, however even videos uploaded directly from the iPhone could not be viewed from Facebook once saved. Facebook 3.1.3 also allows users to write on walls of events and uploads photos with a maximum 720 pixel width. The update also addresses a number of bugs, including problems commenting on photos accessed from Notifications, problems uploading smaller photos, incorrect highlighting and sorting in certain areas, and broken photo album links in the news feed. Notably, Facebook 3.1.3 adds no support for iOS 4, suggesting that the app may have been submitted to the App Store for review prior to the iOS 4 announcement. Facebook is available from the App Store as a free download.
