playing with the CSR PS and not really knowing what you are doing is
dangerous, because you can set your Bluetooth chip to a non working
state. The archive contains some post from CSR guys that may can help
you, but actually I think you broke it. Btw you never had to do this
modifications, because the iPAQ is working out of the box ;)
