I purchased the JB 200i, and was very disappointed with it. I'll post a review sometime. Several problems: (a) iPhone headset (calls to/from the iphone) were mono (and not stereo) using the JB 200i stereo headset. (b) Phone app, Contacts app, Voicemail occasionally crashes when listening to music. And vice versa. (c) Music randomly opens up when trying to make (or receive) and end a call. (d) Many more... Will elaborate later. If anyone's considering buying JB 200i to use for the iPhone, I'd look elsewhere. I read somewhere that the iPhone headset (calls to/from the iphone) can only be mono for bluetooth. Is that true?
