All of a sudden, I cannot hear any ringtones when receiving calls. It worked yesterday, and stopped today. I did NOT download or upgrade anything, nor did I mess with the OS. Everyone else who has this problem had upgraded the OS, etc. If I go to Ringtones, I can play them now (after I clicked Activate Phone), but still no luck when people call.
I have tried a battery pull. I don't know what else to do.
I am using OS 4.61.250.
