Tweetie has been pretty much universally recognized as the best iPhone Twitter client since it launched, and Tweetie 2.0 took it to the next level. In fact, it was so good, that Twitter decided to buy the app outright, rather than building their own iPhone app. News soon came that Tweetie would become “Twitter for iPhone” and would be made free (Tweetie sold for $2.99) to anyone who wanted it. Well, today is that day, as Tweetie 3.0 has been released with new features (we’ve got a list of them after the break) and is now simply known as Twitter. It’s full-featured, it’s the official Twitter app for the iPhone, and therefore it will have access to more Twitter resources than any other Twitter app out there. We recommend it highly, and you can download it now.
