iPhone 4G will support WiFi 802.11n

Next generation iPhone might have support for WiFi 802.11n. A recent Apple job posting shows that such software support might come soon:

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.

The addition of Wireless N capabilities and support are quite logical. Hope to see iPhone 4G soon.
