Can you post or point the way toward how to play with basebands? Or, how you got the baseband to respond over USB? I'm very curious about how these end up working, and can't find much public work in the Android space of people trying to reverse basebands. Edit: I found the 28C3 presentation entitled "Reverse-engineering a Qualcomm baseband."
