I updated to this os a few days now. At first, it mixes my contacts but I resolve the issue doing a second time restore. But now, I'm missing the tune in radio app. I looked on the BlackBerry World and is there but I can't even open it over there. Try to uninstall it or delete it and it told me "fail to uninstall". Any ideas how or where can I uninstall it? I was looking over the settings but couldn't find anything or an app management like in the 7.1os. Any ideas?
