I recently visited my local apple store because there was dust in my iphone 4s rear camera when I got my iphone 3 weeks ago on July 6, 2012, and when I went there the genius opened the back of my iphone 4s and cleaned the rear camera. When I got my phone back there was more dust and a scratch visible in daylight but nearly invisible during normal light conditions. This scratch is extremely irritating, and I was wondering If I could get a replacement? I baby my phone, and I have NOT had this scratch before!
