First and foremost, HTC cannot be responsible for reception difficulties you may experience by the following problems:
1. Using earphones other than the supplied set in the package. Its not anyone's fault that your ears cannot hold them, that is like someone missing some fingers complaining that the phone is not shaped to fit his/her hand. (no offense intended by the analogy).
2. Locations that are not optimum for FM reception. FM broadcast band, generally 88 MHz to 108 MHz, are the most effective for FM reception. The FM broadcast signal is VHF (very high frequency) in nature and generally can only be received within a distance known as "line of sight"... about 40 miles. Without hills, mountains, or buildings to impede its progress, an FM phenomenon commonly known as "diffraction" causes the FM broadcast signal to conform to the curvature of the earth for a distance of approximately 30 miles beyond normal line of sight. It is this phenomenon that provides for long distance or "fringe reception" of the FM broadcast signal. Fringe reception can usually provide a listenable FM signal, although it is often noisy and of low audio quality.
Finally, i get a clean and crisp FM signal on my phone just so you know.
