From 9to5mac -

Per Apple Insider, the soon-to-be-released iPhone 3,1 references the Broadcom BCM4329 wireless chip in the boot script, meaning it has significant upgrade over the Broadcom BCM4325 used in the current version since it adds power savings and new support for 802.11n features, including the ability to find and join 5GHz networks. It also adds the ability to receive and send (versus the current model's receive only mode) info via FM signals.
