This is very bad news for me...
I have a CD MBP (in Denmark) and wish to upgrade the airport card.
You bought the card from a store in the US, right? Can you post a link? I haven't been able to find any on this side of the pond that sells them.
Please also post if you find a solution.
ps. I found
this on Google. Not much info, but it suggests to me that you need to flash the firmware...
Hope you get it sorted out.
Edit: In system profiler, my airport card says Region: Worldwide.
It probably is the joker
