I'm not a cell cracker or EE/RF Engr myself, so I don't know the ramifications of doing such things or if you would just splice off the antenna wiring (thought that was interlinked with the OnStar uplink though).
The advantage is not in software, it's the hardware. A physically bigger antennae than what your phone has. So all we need is to figure out the leads for the 4G antennae. Tapping into them I bet would mean no OnStar since it uses the same antennae. So you really don't need to work on the software side.

I know OnStar uses AT&T networks, so guessing it's sim card based. Not sure if that means it will work for other fequencies like Verizon and Sprint.
