After several attempts to post from the iPhone or iPad, I’d almost given up hope. The latest March 16, 2011 release seems to work much better.
This app could set me over the edge to actually purchase an iPad 2, rather than stick with the original. However, I don’t appreciate taking a screenshot and not being able to clean it up. Eww.
Update: Combine the free app called PhotoPad and the images can be rotated.
