Hi again guys, i have news.

The manufacturer has responded my emails. They said the Facebook contacts problem is due to special characters, including the @ of the email adresses, so it crashes. No problem on that side, i dont mind not having the FB contacts on the phone.

About the A2DP problem, they said thats because the phone is transmiting the "hands free" profile at the same time that the A2DP,
so the radio gives priority to AD2P and nothing can be modified in the radio to stop this.

They said the only way is to disable A2DP in the phone, so the last resource i have is you guys. Anyone??

thanks and more thanks!!

EDIT: Fongo, it does not have an external module, now i see what you mean. The BT module is integrated in the system case itself, and the microphone pops out in the front lid under the volume key.
