From atebits comes this most welcome news:
Tweetie 1 set a new standard for Twitter clients and iPhone apps in general. It proved that you didn’t have to sacrifice intuitiveness for functionality. Today we have iPhone OS 3.0, 3GS, and new Twitter APIs. Tweetie 2 is built from the ground up to take advantage of these fantastic new technologies.
Tweetie is my Twitter app of choice on both the iPhone and the Mac. I’m anxiously awaiting these updates.
