So, I just got an iPhone 4-- love it. I noticed something though. While playing my music, i suspected that only the right speaker was playing sound. So, to test thing, I put my finger over the right speaker, and low and behold, the sound become extremely faint, the LEFT speaker DOESN'T PLAY SOUND. Is this how they work, why is only 1 speaker working? Can someone test this for me? Hold your finger down on the right speaker while playing music, and listen to the left speaker. No sound is coming out of my left speaker. What should I do?
