I know when the leaked OS 6 came out some time back, I found out that my OS 5 ringtones were gone. I don’t know about you, but I have really taken to Star Chime. I went back to OS 5 and back to OS 6 again, but I have my ringtones thanks to BlackBerry. The nice thing about the ringtone package is that it moves even if you downgrade and re-upgrade. It stays in the App Loader.
