Working with Cingular on getting me onto my wife's phone plan, I missed out on the Nokia 6820 they recently had for $50. In case it doesn't reappear soon, I'm looking at other bluetooth-capable phones at Cingular and the Siemens S66 is one option. Does anyone have one of these phones such that you can comment on its usability, and any issues with its bluetooth in the Prius? Thanks, - Leo
