802.11n

A recent job opening posted by Apple on their website may hint at 802.11n Wi-Fi in the next iPhone. After the third generation iPod touch was found to contain the Broadcom BCM4329 chip capable of 802.11n (but only enabled for 802.11g) it was suspected that the faster protocol was just on the horizon. This advertisement, which is looking for a software engineer specializing in Wi-Fi protocols to join the iPhone team, would appear to be intended for just that purpose.

Developers are continuing to dig through the new 3.0 firmware beta and have uncovered two possible new features that may be evidence of an upcoming hardware revision. Driver support for a new Broadcom Wi-Fi chip suggests the addition of high-speed 802.11n Wi-Fi in a future iPhone. Meanwhile, a few new interface elements have shown up on the video uploading screenshot found a while back, suggesting that the next iPhone will have a few basic video editing capabilities in addition to the ability to record and upload video.

Silicon Alley Insider reports that a "pluged-in" source inside the cellular business has information that the next iPhone 3G will have a "significantly faster" internet connection than it's predecessor. It is not known if the source was referring to Wi-Fi or the cellular data connection, but both could potentially be upgraded.
