Very low sensitivity on microphone 3GS
This is my first post here, but I just couldn't stand it anymore. I just got a new 3GS iphone 3.1.3 and I jailbroke and unlocked it for T mobile. Phone is abs. fine but one problem. The mic does not work very well. When I am talking I have to be literally 2 inches away or it won't pick me up.I have to be laying in bed facing the phone, I tried to look up at the ceiling while my phone is on the bed next to me and it wouldn't pick up my voice. I don't know think it is a hardware problem. But I do have warranty on it still, but the problem is I called Apple and they said they wouldn't fix my phone since I jailbroke it. Also they wanted me to update to ios 4. I don't know what I should do at this point.
I am not sure if some of you have had the same problems or not.
