microphone and earpiece not working with phone calls
I have an unlocked IPHONE 4 which is running version 4.0.1 and baseband 1.59.00.
my question is this, When i make phone calls the phone allows me to make the call however i cannot hear anyone and they cannot hear me. however when i make a call with skype the microphone and earpiece both work. i am totally stumped with this. any help would be great. thank you.
Es esta una buena pregunta?
