Para sincronizar por BT podeis probar esta solución (sacado de XDA):
After Pin code 0000 on PPc and PC , left softkey is :"Done" ; right softkey is : "Advanced" , click on advanced , on the next page click in the case "Serial Port" then "Save" , a new page will open and click on the case "Serial Port and "ActivSync" .
Suerte
PD. Para Trinity creo lo consiguieron asignando el puerto serie COM 7.
