The application formally known as Tweetie has been removed from the App Store to make room for the official Twitter branded iPhone app. This app—which is basically Tweetie with a name change to make it official—is now available in the App Store both internationally and in the U.S. It’s labeled as version 3.0 (up from 2.x) which means that along with the re-branding, there are some new features.

Atebits have aimed to keep the interface looking like an Apple iPhone app should look, but ensuring that as many features as possible are included, without over-facing the app itself. I think they’ve done a great job in that respect. With so many new features and a great user interface, I would certainly recommend Tweetie 2 to any iPhone Twitter user.

Tweetie for Mac was officially released earlier this week, and it has turned out to be just as popular as the iPhone version. There are currently two versions available for the app: ad supported or not. However, the ads in the free version can be turned off. When it comes to Twitter clients, Tweetie is as feature packed as it comes; from @replies to direct messages and search, it has it all.
