Hey joey and all others, I've had problems with creaking body of my N9, and also later a crack in polycarbonate near the 3.5 mm jack appeared after 2 or 3 weeks of really carefull using. I went to the shop, where I bought it. They said that they're not going to replace it for the new device and that I have to take it to the service (even though it was apparently a manufactoring problem). I went to service I was sent to and they said, that they don't have spare parts and that they don't know if warranty applies to this problem. They also gave me contact to another service center, which was outside of city. I didn't want to ride somewhere outside the city, when a bought a Nokia premium device, for its premium price and the manufacturing was worse than some lo-end budget phone. So I wrote to the Nokia Care and asked what to do. They told me, that it's non of their bussines plus the same thing about contacting another service center. Than I went to the Nokia flagship store and asked about their opinion (at that time it was just creaking, but quite a lot). They said this really isn't ok and recommended me some higher level service center. So I wrote there an e-mail, attached a video of creaking and asked what to do. They replied, that they have to see it and that anyway, if I want to change the phone, the seller has to take it back, but they also wrote, that they can make me a (paid) review if the phone is suitable for exchange. I took my phone there, they took my 500 CZK (something like 25 USD) and wrote, that the phone is defective. So I went back to the seller and told him about the problems with the phone - again the same thing about service, blahblah, so I showed him the review and miraculously, with the review in my hand, he changed his mind, took the phone and sent it to Nokia for assessment. After very painfull 2 weeks with substitude Android device from my drawer I got a new device. No creaking, no cracks, yeah!

For the ones with creaking phones, I'm attaching the link to the video of my creaking device at the end of my post. After all it seems that creaking and craking isn't the regular "feature" of N9 and if problems with the device aren't caused by your fault (dropping the phone, etc.) you should get a replacement. Don't know how it's at your contries, but we also have a law here, which says, that the seller has to refund all the money you spent to prove your warranty is authorized - well in my case, they (Electroworld, quite huge international network of shopping mall-like shops) didn't Anyway I'm not going to sue them because of 25 bucks, just think twice when you're choosing a shop for buying your N9.
