Wow, that’s kind of frustrating. Yesterday I tried my headset I used for many years on my iPhone4 and everything worked – except the mic. I can use the volume buttons and also the third button on the remote control for starting/stoping music and to skip to the next song worked (with Spotify at least). If anyone has a fully FP2 working headset with remote controlls and mic, which one is it? Or did you just get an adapter to get your old headset working?
