I've installed an Android app called "TuneIn Radio", which can be used to listen to many radio stations via the Internet. It's available in the Android Market.
The problem for both is the antenna. An antenna for FM radio is much larger than for cell phones or WiFi. An AM antenna is much, much larger again. While it is possible to use some methods, such as loading coils, to improve performance, there is a limit to what can be done in such a small package. My Nokia N800 uses the headphone cable as an antenna for the FM tuner.Now is there a reason why some phones will have an FM tuner, but never an AM tuner?
Is the antenna within the unit? Or does it use the headphone cable like the Nokia N800? Antenna sizes are very much determined by the laws of physics. An antenna for FM would be about 10x or 20x the size of one used for cell phones. You can use loading, but that reduces efficiency and also takes space. You could use high gain, high impedance amplifiers, but that leaves you wide open for interference problems.If an FM tuner and antenna can be squeezed into that new
