I'm planning to get a bluetooth headset for use with my Eris. I don't really have any experience with a headset so I have a question about how it works: I would like to leave the headset powered on and when I receive a call, either answer it from the headset or from the Eris depending on where I am/what I'm doing etc. Is this possible? Or if the headset is on will I always have to answer the call from there? I believe that I've heard that this is the way headsets work but I was hoping that I might be able to choose my answer "mode". Thanks.
