In September, Tweetdeck updated their desktop application to allow users to view their entire Facebook feed next to their Twitter feed. Given that it’s probably the most popular Twitter desktop application, Facebook support became extremely useful. As of today Tweetdeck’s iPhone application now provides support for Facebook as well, letting you view and update your Facebook stream while on the go.

While the Facebook for iPhone application is already one of the most popular iPhone applications, having a single application to manage all of your social activities is definitely useful. While I’ve personally stopped using the Tweetdeck for iPhone application and shifted to using Tweetie 2, there are still plenty of iPhone users who enjoy the features included within Tweetdeck.

One of the most popular features on the Tweetdeck for iPhone application is the ability to sync columns with the desktop version of the app. This latest update also includes support for the landscape keyboard, which is something I know many users prefer. I’ve also included a video below which highlights all of the new features in the Tweetdeck for iPhone application update.
