Well i just got my replacemnt again for like the 5th time and its a 9C82 and of course was terrible yellow on the bottom, but i called the same guy that took my engineering hold and he was very apologetic and he offered me a RAM upgrade to get the 4GB ram so i took it, im very happy they offered me this but i really hope i can finally get a non yellow display. I really dont want to have to ask for a refund but im tired of going through this, so heres to hoping my new fully maxed 15" MBP will have a good LCD.
