Nope. Mine is flawless as can be.
Try pushing in the middle at the bottom on the back of the phone - does it bow in slightly then ping back and make a noise?

My iPhone 4s is making the same exact noise. I first noticed it when I was typing. When I would press to type, the pressure from my hand holding the phone would press against the back and cause the noise. Then I narrowed it down to the back. I took it to the genius bar and of course the noise wasn't there when the genius looked at it. He just removed and reinstalled the back. The noise is still there and I am going to go back to the genius bar and hope for better results.
My 4S does this as well! Anyone know if they Apple Store will repair/replace free of charge? I'm certain I didn't cause this to happen..
