I don't think there is a current android binary posted, just the one on page 3. I mentioned a few months ago about buying the bluetooth transceiver from dealextreme. These are HC-06, at least the one I got. It seems to work, but had to comment out
pinMode(btResetPin, OUTPUT)
from the firmware otherwise the module would not turn on. Also had to remove the semaphore from the bluetoothSerialService class or the app will hang. I ordered HC-05 modules from Banggood.com last week.
