What kind of crack are you smoking? The iphone 3GS does NOT have the Broadcom chipset you reference! If it did, it would have Wireless-N which would be AWESOME because I could finally disable G on my router at home and still be able to get wi-fi on my iphone!!!!!

No, that's the chipset, speculations about my hypothetical drug use notwithstanding. As was the point of my previous post, the fact that the chipset has the capability does not mean that its features are currently fully utilized.
 
An iPhone 3GS teardown with detailed chip analysis shows that the 3GS contains a different Broadcom part than the 3rd generation iPod touch: the BCM4325. According to Broadcom's product page, this part truly only supports 802.11a/b/g (no n), in addition to Bluetooth and FM (receiver only).

So, yes, the 3GS contains a chip which could be used to receive (but not transmit) FM radio. That being said, the chip by itself is useless unless the correct antenna is hooked up. So far I havn't read about any evidence to suggest the presence of such an antenna connection.

I don't know how the hardware is setup but alot of manufacturers just use the headphone cable... not sure if that would work this time though
