Awhile back Twitter launched and started promoting Twitter for BlackBerry. Shortly after that they bought Tweetie 2 and proclaimed it would be renamed Twitter for iPhone and be free one day soon. That day is near as Tweetie 2 has disappeared from Apples App Store. Rumor has it that the new version, which will be free, should show up tomorrow in the App Store as Twitter for iPhone. TechCrunch eludes to there possibly being a universal binary of the application meaning it will work on both the iPhone and iPad. Either way, keep your eye on the App Store for the update.
