They said at Macworld that an enabler would be provided with the new 802.11n-based AirPort Extreme Base Station coming out in February, but were mum about how other Mac owners would turn on the faster Wi-Fi mode. iLounge reported last week that two unnamed Apple employees said the company would charge $5 for the enabler because of Sarbanes-Oxley accounting issues related to adding unadvertised functionality to products already on the market. Not charging would apparently require restating earnings, or at least that what was said. A reader of my Wi-Fi site sent me a response to his question about this to Steve Jobs: Jobs said, "It's the law." (The email headers were included and check out as legitimate Apple-originated email.) Of course, the enabler isn't serialized, so once it's out, anyone can use it, but it's an odd twist."
