Okay, so I'm just trying to get a handle on this question. I have a Logitech Bluetooth headset that I've used with my cell phone for a couple of years, and I was intrigued by the idea that I could pair it with my iPod Touch. I thought that I might even be able to use the mic with the new Voice Memo app. But, when I put my headset into discoverable mode and set my iPod to searching, nothing appears. So, this leads to my question. What will and won't work? And, if anyone cares to shed some light, why? Thanks!
