I did what you said, I updated from 3.1.3 to 4.0.1 and then when I tried to reload the app the system said I need to update my software to 4.1 to re-download the app!!!??? I'm not wild about upgrading to 4.1 or later on my iPhone 3G due to perfromance issues. Why could I use the app in 3.1.3 but not 4.0.1? $29.99 wasted...Money back???
