If only the results of swedish experiments with iPhone 3G could be comparable with the results of FCC tests, iPhone 3G S seems to be sporting considerable better radio:
iPhone 3G S FCC tests, page 23; output power (OP) in UMTS 1900 tests, dBm, where f stands for frequency, MHz:
802.11n is still a generation or two from realization into mobile devices. It is power hungry, hot, expensive (relatively), and to get the benefit it typically requires multiple antennas. The last part is the most critical, because handset designers value space religiously.

I'm not sure about everything in your post.
Broadcom claims to have ready-to-use solution.
BCM4329 with 802.11n seems to be quite similar in all other aspects including shared antenna to actual 802.11bg chip (BCM4325).

This may mean that iPhone 3G S may be quite valuable upgrade, just having been terribly presented.
OK, now I'm just waiting for the conversion of battery life duration from "hours of talk" into "days of average usage".
Ummm... iPhone 3G S has solid chances to become interesting...
No hidden 802.11n.

Where's WiFi chip, by way?!
