I haven't had the pleasure of testing a cell phone with FM built in.  But, my educated guess that none of have useable reception unless headphones or earbuds are plugged into them.  Why?  Because physics dictates that an effective antenna for VHF frequencies can't be built into something the size of a cell phone.  How many people keep earbuds handy at all times?  I know I don't and I don't know anyone that does.  FM in cellphones would be nice, but claiming it to be essential for emergenies is a non-starter because it simply won't function for most people.
 
Many stations have apps available to play their web streams on smartphones.  Mine does.  I don't need FM reception to hear any of the news radio stations on my phone.

And I respond:

The idea of FM in cell phones being a non-starter due to ineffective antennas sounds familiar from someplace.....  Lowell is correct though.  My cell phone does have both an FM radio and a basic app to run it.  But the app won't even start unless there are ear buds plugged in.
