I wish Apple would enable FM reception, or a least broadcasting to a local (car) radio. Anyone know of an iPhone hack?

There is no hardware to support FM transmission (only receive) and just because the Broadcom chip has an FM demodulator, doesn't mean that you have enough hardware to support FM reception. You need a substantial set of antenna tuning components, not to mention the antenna itself. Those pins are not broken out of the logic board so it would be near impossible to implement this mod -- even if you were willing to open your new iPad and take a soldering iron to it!
