Why does my iPhone 5 rattle?

Okay I received the iPhone 5 last week and I really like it. The phone is super fast and functions well. However today I noticed rattle noises from the camera lenses. It can only be hear if I touch the Apple logo on the back or shake the phone back and forth. I understand this isn't a major problem at all. In fact many iPhone users has it. It is a camera lense that is required to be a little loose

However I think it is annoying to experience this when I spend over +1000$ to buy this piece of phone. My question to you is: "What is your experience with this rattling? If you are an iPhone user, does your phone also rattle or not?

You spent over $1000.00? I want to hire whoever convinced you to pay over $1000.00 for a $650.00 item.

That "rattling" is the image stabilization system. It keeps your video and photos clean and clear, so be glad it's there. A rubber case would probably block the sound a bit. I'd try an incase
