Stereo Bluetooth Adapter

[ptb6744#IM]

I read somewhere that there is stereo bluetooth adapter for the iPhone 3G. I was wondering if anyone here used it and if so how did it work?

I just switched from a Blackberry Bold to an iPhone 3G 16GB version. This is like the 3rd time I have purchased an iPhone on this line as I have a tough time making my mind up between the two. This is a great site for all info on the iPhone!
