SiliconRumors (formerly MacScoop) reports that Apple is preparing an update to the MacBook Air that could finally include built-in 3G wireless networking.

The most notable feature our sources expect to be added to the new MacBook Air is a built-in 3G modem allowing connectivity to high-speed cellular networks.

The rumor site also suggests that the entry level MacBook Air could find a lower pricepoint between $1300-$1500. The possibility of 3G in future Apple laptops has been suggested before through both job descriptions and evidence in Snow Leopard.

Apple has already released a minor update to the white MacBook today and there have been rumors that they be readying more update for WWDC. SiliconRumors was formerly known as MacScoop which has had some reliable information in the past.
