Next iPhone to Support 802.11n Wi-Fi?

Specifications contained in the iPhone 3.0 firmware indicate that it will support low power 802.11n wireless networking, according to an AppleInsider report.

The new version of the existing Broadcom chip that supplies WiFi and Bluetooth on existing models jumps from BCM4325 to BCM4329. The component upgrade adds new support for 802.11n features, including the ability to find and join 5GHz networks. 

Existing iPhone and iPod touch models only support 5GHz 802.11a networks, or 2.4GHz 802.11b/g networks, forcing users who want the top speed of 802.11n (available on all MacBooks) but compatibility with 802.11b/g networks (to use the existing iPhone) to set up a 2.4GHz compatible network. That compromise forces the wireless network to deal with interference from other networks on the often crowded 2.4GHz band.
