does your iPhone speakers play out of one speaker only?

Yes, but I think that is how they are supposed to be. I assume that the other side is your receiver. This is pure speculation though.

they all do

The iPhone has one speaker at bottom left and one microphone at bottom right.

I am so glad you asked this question. I thought mine had a defect. I was actually going to take it in tomorrow.

thanks guys!

im glad you asked and thanks for the answers, i thought my right speaker was blown..thats good to know…too bad the speaker volume is so low tho…

yeh me too i was gonna take a visit to the apple store as i thought the speakers had blown what a relief that the phone is not knackard already.

wow, i always assumed mine was broken. mine comes out of the left only glad to hear this.
