To use a regular phone you would have to reverse-engineer a significant part of the (low-level) software, est. cost > $1m Even then you would have to get lucky with the hardware, as it is not designed to sniff all the meta data and pass it up for capture. It might do some of the stuff in hardware that you want done in software.
