Why does iPhone 4 have LEFT and RIGHT volume CONTROL if it got one speaker?

If you plug a stereo earphones plug into the 3.5mm headphone jack socket, you'll get STEREO…

That's "why", LOL!

  • Why is my iPhone's left speaker (for sound) not working? I had recently damaged my phone by dropping it on pavement (approximately 3 feet), and it slid about 20 feet. Just today, I noticed the the left speaker on the bottom of the phone is not working. I have a feeling that it's not working because of the impact of the phone falling (I had a snap-on case at the time).Is there any way for it to get fixed without replacing the whole phone? And are there any good websites for parts? -Thanks
