Starting today, August 31th, 2010, Twitter is switching off basic authentication for third-party services. This means all the Twitter upload services in Sparkbooth 2.2.1 or lower will no longer work. If you want to continue to use any of these Twitter upload services, please download and install Sparkbooth 2.3 Beta. TwitrPix, Img.ly, MobyPicture, Posterous, TweetPhoto, TwitGoo, TwitPic, and yFrog have all been updated to use the new OAuth authentication method now required by Twitter. Unfortunately, ScreenTweet, TwitDoc, and TwitSnaps have not updated their services to use the new authentication method, so they have been removed from Sparkbooth for now until they have been updated.
