I noticed two speaker grilles - either side of the dock connector on my iPhone 3G. While playing any sound, if I put my finger over the left grille sound all but disappears, I can still hear a little but only high frequencies from the right grille. If I block the right grille, I hear no difference. So the question: are there two speakers in the bottom of the iPhone 3G, and is one of mine possibly damaged? Any fix, other than replacing the dock connector assembly? Thanks in advance..
there is only one speaker in the dock connecter of the iPhone. That is placed in the left side of the phone and right side one is mic. there is no two speakers in the iphone
