I figured that seeing as there's a lot of people in here running 4.0, we may as well start a list of apps that have issued under OS 4.0. For example - Reeder now crashes at the end of its sync. It's fine otherwise. Gowalla has all sorts of graphical corruption, as if some assets are missing. Mail (yeah, MAIL!) isn't pushing my MobileMe email consistently. qStatus - when uploading an image to Twitter, the app thinks it's a video clip. TumblrGear is borked. Tweetie 2 crashes when searching. We Rule doesn't let you buy anything, list is scrollable but clicking on an item does nothing. Now I know things like this are to be expected - I just thought a list may come in handy for some people, devs included.
