Yes you will still get the bluetooth function.
Btw i create an rgn firmware with thai's 1460 2.80 and flash it into my 1360T (twn) it flash ok. I have all the function of the thai 2.80 (ecoroute, thai jcv, etc but i lost the thai menu and the thai keyboard dont' load -which is weird-).
If you can get thai menu to work please tell me.
