Red Mercury

Well, my antique cell phone has just about given up the ghost. I'm planning on buying a new one, and I'm considering the concept of hooking up the phone system in the TT.

A few questions arise:

1) I have a Roadster. Does anyone know how well the built-in microphone works with the top down, but the windows and wind-screen up?

2) Does anyone have a recommendation of a phone that works particularly well with the Roadster? I've seen references to the Nokia 8260...

3) Do any of the Orange County viewers know of a place to get this done?

Any opinions are appreciated...
