Hello. I have had my iphone4 for about a year or so. just today the ringer quit ringing unless I had the earphones in. When I go to sounds to test my ring volume, it rings then without the headphones just fine. My music also plays just fine. I have also lost the keyboard "clicking" sound, and the click you normally hear when you turn the phone on or off. I have never used my headphones with it, but I tried the trick of inserting and removing the headphones jack several times, but that does nothing. I have also completely restored my phone thru itunes and got nothing. Any help???? PLEASE????
