Hello, About 7 months ago I purchased a refurbished IPad 4 from the apple website, and, a week or two ago, I noticed a few small specks of dust and one quite large and pronounced one. I can't be sure how long those dust specs have been there but I only noticed them because I had purchased a microfiber cloth and cleaned it for the first time. This may not seem like a big deal to most people, but my OCD makes my eyes go straight to where the dust is. My question is: can I have my IPad replaced under free one year warranty? I think that I should also mention that I somehow acquired a 1-2 mm deep scratch on the bottom right corner of the screen, the part that displays not the border. Thanks for any help!
