I have just read of another member having this problem, mind you he was JB but how he solved it was by restarting his iPad. Press the top right button until the slide appears to turn off your iPad, wait for the Whirly to disappear and then restart by holding the button in again until the Apple logo appears. When the ipad restarts long press the offending app until the cross appears and then delete it. Give this a try, let us know how you go.
