If you're a TweetDeck for iPhone user or have been clinging to the Adobe Air version of the app for dear life since the native Mac version debuted, we've got some bad news for you. Twitter has decided to end support for those versions, along with TweetDeck for Android. You'll be able to download them until early May, but after that they'll cease to function. Since these clients also rely on v1.0 of the Twitter API, which is being retired soon, they might experience connection problems in the run-up to their removal.
In addition to killing the iPhone and Air apps, Twitter is planning to remove Facebook integration from all versions of TweetDeck. The company says that it's making these moves in order to "focus our development efforts on our modern, web-based versions of TweetDeck." This means the web-based and Chrome extension versions of the software, although the native Mac app (shown above) will also continue.
