I am new to the Hero scene and have a question that I hope someone can answer I know that you can connect a bluetooth headset to the Hero and use for phone calls, but can you use the bluetooth headset as a microphone for other apps? specifically, I use an app (speakwrite.com) that does text dictation. I would like to use this program on the road as I drive. as it is now, I have to speak into the mic on the phone, but would like to use an external microphone instead, either bluetooth or corded. Any help or ideas welcome. Thanks!
