I have biteSMS. This problem didn't start until recently. When my iphone receives a text, it doesnt ring unless Im inside the actual bitSMS application. On the lockscreen it doesnt ring or light up. Using SBSettings I managed to track it down to the mobile substrate plugin biteSMSsb. I would just disable it, but it includes most of the core functionality (Quick reply and Quick compose.) Does anyone know how to fix this? The only things that have changed on my iphone is I installed spire but I tried uninstalling it and it didn't fix it
