Nope. Supposedly Intel cpus 2011 and newer have a 3G capability.

Absolutely BS. I WISH it was true, it'd be friggin awesome to have that functionality built in.
This is covert transmitters, according to the NYT. Basically hiding small transmitters in USB cables, flash drives, etc. Not at the manufacturer level, apparently. Hell, that's been done for sixty years in various forms. I've seen Wifi enabled hardware keyloggers at Defcon for over a decade. You can now buy them online for about $100. Hell, they make keyboard keyloggers that look exactly OEM. The boards have the keylogger integrated in them, and it's pretty damn subtle. 3G, GSM or alternative frequency hardware keyloggers aren't exactly rocket surgery.
Meh, this is even more boring than covertly enabling WiFi on laptops.
Disappointing.
