No sounds during call
'''Hello,''' I want to buy an iPhone which has a problem : During calls there is no sounds (the caller don't hear me and I don't hear the caller) even if we put the headsets or the loud speaker mode... But when we use the net or a VOIP app it's work fine... So, I want to know only if it's a motherboard problem or changing the mic,speaker...etc will fix this. '''Thank you.'''
