It was almost one year ago that we posted TweetDeck might develop an Android app and now the beta client is finally available. TweetDeck brings all your Twitter, Facebook, Buzz and Foursquare feeds into the same column and provides a slick UI that puts the key features at your fingertips. In order to receive the beta, you must visit
http://www.tweetdeck.com/api/android_whitelist/ and sign in with your TweetDeck account. You will then receive an email with further instructions and a link to download the app.
