Digg founder Kevin Rose got his hands on the beta for the iPhone version of TweetDeck, proclaiming that it will soon replace tweetie as his go-to app.

If it works anything like the desktop version, I will also be making the switch. Apparently, the app version features the same column-based friend group structure as the desktop version, the ability to synch with the desktop version, and Facebook-esque status updates. Unfortunately, the "when" and "how much" part of the question remains unanswered. Hopefully, we won't have to wait long.

UPDATE: The app has been released—and it's free. [iTunes and Kevin Rose via Digg]
