I thought that this has just been explained.
The MW and LW antenna is different from the FM antenna. To add a MW antenna
would require adding a ferrite rod and coil. This would add to the bulk and
weight of your phone. You like the phone small, no?
However if you use a headset you can double that for an fm radio antenna,
there are loads of cheap FM only radios that use the headset as an antenna.
It is a clever additional functionality and you get the headset free!! I
have no grumbles with the radio.

So that people can play the radio through the loudspeaker without
needing to have the earphones hanging off the phone.
