With respect, Sensei... as we say in the church, "you are preaching to the choir" - I have understood physics since middle school and have some experience in FM radio stations since the early '70's.
Wavelengths are different but I find it difficult to believe that the chip remains and the antenna length to receive doesn't from the known fact of Apple testing it for iPhone and its existence on the iPod as we speak.
If you know for a fact that the antenna does NOT exist in the iPhone (where the more expensive chip set does) - we can put this part of the issue to rest, to my satisfaction at least. I can read the signs (or lack of them) clearly - it is not about the tech.
It's easy to see that an FM antenna doesn't exist in the phone. Just go to any site that has done a breakdown of any iPhone.
I've never heard that Apple tested it, but I'd be happy to look at a reputable source.
What "more expensive chip set" are you talking about. There is ONE chip that provides WiFi and Bluetooth. It's a Broadcom BCM4334. Not a chipset. It also provides FM receiver and transmitter capability. I have the data sheet for it. It has 12 connections for the FM function; 2 for antenna, audio out, FM transmit and 8 for control (frequency selection). It's not more expensive than anything. There are competing chips; all of them provide the same functionality. There is no reputable engineer who would implement connections on a very dense circuit board for a function that won't be used. So, while I can't prove that it is not wired, into the phone, it is extremely unlikely that anyone would have gone to the trouble for a function that Apple did not plan to support.
