I thought Peep wasn't working (which is the DEFAULT Twitter app), which is different than Twitter. The article above is talking about HTC Peep not working because HTC didn't update. The Twitter app (from Twitter, not HTC Peep) is working for me, and should be for you unless there is a different problem. The app I am talking about is the one with a blue and whilte lowercase T as the icon. Otherwise, we are talking about different issues... sorry!
