When Twitter swallowed Tweetie maker Atebits, they declared that an official Twitter client—a la Android's—was on its way. You'll be happy to hear that Twitter has barely changed the iPhone's best Twitter app, except where it counts: Price.
Woah! Apparently Twitter has snatched up the company behind popular desktop and iPhone Twitter client Tweetie. Twitter intends to "offer [the iPhone app] for free and rename it Twitter for iPhone."
