So I tried changing the tones on my phone for my SMS. I replaced the original tones with 5 custom tones which all work fine when going into the settings app. I can hear all of them correctly and I even changed the labels by editing the sound.strings file in Applications/preferences.app/english.lproj. Issue I'm having now is that now, whenever I receive a SMS, I get no sound as well as no notification that an SMS was received. I'm currently using Notifier+ for my notification on my lockscreen and it has been working perfectly prior to all these changes I made. I tried reverting the changes back to what they originally were and resprung however I'm still getting no tones whenever I receive an SMS. Does anyone know what I could be doing wrong here? Thanks.
