afaik the package included a wired headset too.

resellers of the fr do imo offer the matching headset.
for other see either the archives or the wiki. there have been lengthy  
discussions about working headsets and pinouts months ago and i think,  
someone has compiled that information into a wiki article.

should depend on the pin.

sure, but i am not sure, if handsfree equals headset. at least headphones  
are forbidden (even for bicycles, but nobody cares).
