The best part of this thread is the guy who "liked" the original post. Why would you like someone having issues with their phone?
It's like on Facebook: someone posts bad news, and 5 people "like" it...
edit: My 920 is solid as a rock. If mine creaked as bad as you are saying, I'd return it. Of course, you said all you have to do is pick it up to make it creak, and quite honestly, that sounds really hard to believe. It's not that I don't believe you, but you've had two 920's, and both of them have creaked when you picked them up?
