I bought my ipod touch at the apple store on friday, and over the last couple days I've noticed that it shows dark colors and blacks really badly. My serial number is 1A737A17W4N. Do you guys think I got a bad one? If I did, will the apple store let me exchange it even though it has been opened? If I paid the price difference do you think let would let me get the 16 GB verison instead? Sorry about all the questions.
