I found this guy on ebay who was trying to figure out how to charge and stream his wireless Bluetooth audio device. After looking at his ad and seeing that he offered a return policy, I decided to try it with my Surflink Mobile and it works! I can now charge and stream with my Surflink Mobile at the same time. Totally worth the $50 plus shipping cost.
I know a lot of people have been trying to do this; it looks like he only has 2 more left as of today. Here is the link if anyone is interested.
