iPhone 3GS – Only 1 Speaker Working

Ok, here’s something I didn’t know and just found out. Apparently, on the 2nd generation iPhone and the 3rd generation the left side is a speaker and the right side is a microphone.

I had a first generation where both sides were speakers. The microphone must have been the normal phone microphone or something.

So that’s how it is.

This seems to be the most popular iPhone question out there. :-)
