As of this previous Sunday, 100 Hour Board for iPhone was updated to version 1.2. This update includes support for iPhone OS 3.0, improves the rendering of quotes in Board posts, and teaches the app to remember where you were when you last closed it. There are also a couple minor user interface tweaks; notably, when posts download they should appear in the list with a smooth animation.
