Rooted Inspire and ATT update

Ok, I wasn't paying attention when I got the message about the download available from AT&T. My phone is rooted and it downloaded and attempted to install the update. I managed to un-brick with CWM, but now I have the annoying symbol at the top in the notification area that keeps telling me that the update is ready to install. The clear notifications button won't get rid of this one. Any ideas on how to get rid of the downloaded file and the nagging notification?
