iFixIt has discovered a Broadcom 802.11a/b/g/n chip in the just-announced iPod touch (32 GB and 64 GB) models that uses single-stream 802.11n. Single-stream doesn't get the full power of N, but it boosts speed enough that — along with space-time block encoding, a feature coming soon to Wi-Fi access points with two or more radios — the iPod touch could be an effective networked media server, for streaming and transfer, possibly through the new iTunes Home Sharing feature
