I have a 2g Iphone and it doesn't ring when people call. Alarms work. music plays everything works well. YEs i have made sure it's not on mute or silent. I made sure the volume is turned up. Any one has similar problem please let me know what else i can check i have a feeling it's an hardware issue but i didn't really wanna go ripping apart the thing unless i have reason too. It has the latest OS on it.
