I discovered last night as I was booting up my new iPad 2 there are yellow tinting on the sides of the unit. I said to myself no way but then I decided to power down and power up again. Yup. Yellow tinting on the corners and just above menu button on screen. I read somewhere not to return it as chances are I won't be getting any replacement in a month. Should I call Apple about this issue then? What do I do?
