Focus issue with 4S camera

I seem to be having a focus issue with my brandnew 4S. The examples below are straight from the camera. As you can see, one side of the image is blurry while the other side isn't. When I turn the phone upside down and take an identical picture, the blurry part is on the other side.

The auto focus and tap-to-focus give the same result: I get the blue square that lights up as if it's confirming the proper focus, but in reality, it's not in focus at all.

Some extra single shots, all taken with volume buttons at the bottom so blurry side is on the right:

I've already tried with other camera apps, installed 5.0.1 and completely restored the phone. Nothing helps. Should I call Apple and ask for a replacement? I live in Belgium, so no chance to talk to a Genius in person.

 

Thanks for your replies, much appreciated. Now I feel more confident about calling them.

And yeah, I had removed the plastic. I even tried without my Griffin sleeve etc... no use.

 

Just a quick update here in case anyone with the same problem stumbles upon this thread...

I took the iPhone to one of the Authorized Service Providers here in Belgium and explained the problem. I had to leave the phone with them and 2 working days later they e-mailed me saying that my replacement was waiting for me. No charge of course and the camera of the new one works like a charm.

Excellent service!
