FCC Confidentiality
What Apple have requested is the same as any other company would request and is allowed under the FCC rules, the sensitive information that could damage Apple is allowed to remain confidential. Any information that the user could get by purchasing the product and looking for themselves cannot remain permanently confidential.
Once the product is known to the public irrespective of whether it is on sale, short term confidentiality ends.
These rules are for any company obtaining FCC certification for a radio transmitter and Apple is not getting anything special, just what everyone gets.
So for all the people who do not understand what the FCC does/does not allow, you've had a quick lesson. I do not work for Apple or really like their products but in this case we all get the same, like it or not.
