Just the other day, i noticed that i couldn't hear my caller via the front receiver. but i could only hear from earphone and speaker. I tried plugging in and out (that's what she said) the earphone jack and it doesn't work. i've also tried restarting the device like 5 times and it still doesn't work. Restoring to factory default doesn't seem to work either Anyone have any suggestions? otherwise, i'll just take it back to apple. and see what they can do about it ($50 says it will work there) P.S. i also hear 'rattling' on top of the phone. probably just the camera lens from what i have read. or it's the receiver Any help/suggestions will be appricated.
