Hello. I have a mid-2010 Macbook Pro, 13". Recently my AirPort card has died, I took it to the apple store and they confirmed it. Both apple and Apple Repair Centre are quoting ~£100 for both the part and repair. Happy to do it myself. eBay has plenty of airport cards for macbook pros I'm not entire sure on which one to choose- I assume the ones from the earlier or later unibody models might not be compatible? Please advice if there are any guidelines for this. thank you.
