This is what I returned my 1st one for. If you are holding the phone in your right hand. take your thumb and press the spot right where the memory card goes in (under the batt door obviously). You may get a click or pop. If it makes that sound turn it over and press under the HTC logo. You may get another click. The first one did all the second one does it only with moderate pressure 1st spot i mentioned. Not a big deal to me because i'm not gorilla gripping my phone in one location. The 1st handset was annoying because it would happen on a regular basis with normal usage.
yeah, mine creaks on the opposite side of the volume rocker, so every time I use the phone I get the annoying noise. I called HTC and to buy a new one it's 30 dollars for a piece of plastic. Hell no. And I can't even go to verizon because they still don't have the phone in stock.
