Overclocking
Currently I have one my engineneers attempting to convert the program provided by qualcomm for over clocking and testing the Processors into a smal cab file that could be used for over clocking the pro. But he is also making sure it can be safe done and not risk the device but wheres the fun."
But he disappeared long ago and hasn't been seen since IIRC.
