I have been on a bit of a wallpaper kick this past week. I really wanted a dark themed Drupal wallpaper and couldn't find one. I created my own using the striped black background and the Drupal logo EPS file from drupal.org.
Ever since the iPhone 2.0 firmware was released, I have been searching for a native Twitter app that will give me most, if not all, of the features included with the great web based Twitter app, Hahlo (www.hahlo.com). The main advantages of a native app is that you don't have to fire up Mobile Safari and your account information can be saved in settings.
