After the iPhone 3.0 firmware update, we wondered whether the the next gen iPhone would bring a new chip with support for 802.11n. Now a job posting on Apple's website is feeding that theory.

We've already seen that the newest iPod Touch has a Broadcom BCM4329 chip with support for 802.11n and FM transmission—something missing in our most recent iPhone generation—but we've also learned that the hardware is dormant, perhaps to be brought to life by later additions in software support.

A recent Apple job posting teases that such software support might come soon along with some kind of upgrade allowing for 802.11n capabilities in the next gen iPhone, because it's asking for a Wi-Fi software engineer to join the iPhone team and bring experience in:

• Implementation of 802.11 a/b/g/n & related specifications.
• 802.11i/802.1x Security protocols
• Good understanding of wireless RF technologies & co-existence issues of 802.11 PHYs with other Wireless interfaces like Bluetooth.

Ooh la la. Yes, it's just a job posting and pure speculation regarding what we'll see in the next generation of iPhones, but addition of Wireless N capabilities and support are a logical addition and seem rather likely.[Apple—Thanks, A!]
