My Twitterberry application on my Curve 8330 has been acting weird lately, so I tried to delete the app and was going to re-download it. I deleted it from the application list, and the phone re-started. When the phone rebooted, the application was still installed and still working, but it wasn't in the application list. I did a battery pull, and same thing. It's still there, acting weird, and I don't know how to uninstall it at this point.
