I just recently received the official Samsung Galaxy s3 JellyBean (Android 4.3) update from Sprint. It sounds like this update has been riddled with problems and was even temporarily pulled until the issues could be resolved. I seem to have gotten the latest iteration and things have gone fairly smoothly, except for one extremely annoying issue: I have two "file download" notifications that won't go away no matter what I tried.
Luckily I found this solution on an Android blog from user disgustinglyrad.joe

Finally, no more stuck download notifications!
