I picked up the Excelvan ELM327 v1.5 Bluetooth Mini Small Interface OBD2 Scanner Adapter (link) for the Torque application on my Samsung Galaxy S2 Android phone. I have been interested in getting one of these, but the prices were entirely too high…until now. I paid under $20 shipped and it is working extremely well. Installation of the application on the phone is easy and cheap ($4.99). I’ll post some pictures soon.
