would an FM chip in cell phones receive HD FM channels ? (HD1, HD2, HD3, HD4 )

It doesn't sound like it. It seems they're still thinking of analog. My old Motorola Moto X phone had analog FM. Had to wear ear buds for the FM to work because the long wire of the earbuds was the antenna. Hopefully, they will have figured out a better antenna arrangement for the next gen of phones--should they include FM. Even though they've improved the efficiency of the chips since the days of the Zune HD, I'm thinking that the processing power needed to decode digital radio would still pose a significant battery drain.

Apparently, the Europeans and Australians want FM on their smartphones too:

No

Whether analog FM or digital HD Radio, the earbud cord as antenna will remain -- the underlying physics of how radio works pretty much dictates that you need a fairly long antenna to get decent reception at 88 to 108 MHz. A small built in antenna that would fit inside the phone would probably give you decent reception within about 15 miles of a full Class C FM station.

That said, the chips in cellphones are generally only for analog FM, not digital HD Radio.
