Thats not true. There is an internal quality program and this was extended to cover the cracking in the clamshell hear the hinges. I have the repair reciept to prove it. This is a common fault with all white unibody macbooks mid 2009 and mid 2010 models. On the day I visited the covent garden apple store (last Monday the 17th) there were 6 other people at the genius bar with the same white unibody macbook model all displaying the same fault of cracking in the clamshell near the hinges. The rubber bottom replacement program is a completely different program and has been made public as apple considers this a user replaceable part.
It is true. Of the last 5 we've submitted to Apple, 3 were declined. There's no official program. It's case to case assessed.
