Do you remember Tweetie for iPhone? I do. It seems like the revolutionary (and best) Twitter app for iPhone came out forever ago, but it was only 2008 when the app launched.
Jeremy Stanley wrote a nice article detailing the history of Twitter for iPhone. His piece takes me back to a time when pull to refresh was new and shiny. It is amazing to think about how far iOS apps, and the app store in general, has grown since Tweetie 1.0 hit the App Store.
