Just days after a prototype MacBook Pro with a built-in 3G antenna appeared for auction on Ebay (since removed), the company has been granted a patent on an integrated wireless antenna system that is "hidden" in keys on a notebook keyboard, perhaps demonstrating a superior way of adding 3G (or other wireless) communication to future models. The patent lists Wi-Fi and Bluetooth, but also mentions GPS and 3G as possible connections, AppleInsider reports.
