I frequently work in an area that has very good GSM coverage, and no Sprint coverage. I'd really like to be able to roam to the GSM tower, but I only have the SIM card that was included with the phone.
Any help would be greatly appreciated.

You need to remember that on Sprint's TP2, there is no network (SIM or Subsidy) lock on the GSM part. What the manufacturer did is they added some sort of system to check if the device is a Sprint-branded AND if it is going onto a US-based GSM network (doesn't matter if its home-service or roaming onto), then it simply refuses to work.
So as someone above answered what you need to do is apply the security unlock and flash a patched (tweaked) radio for Sprint's TP2 so it would allow you to use US-based GSM networks.
And as for using your CDMA's phone number on GSM network? Not going to happen, at least in the States it's not. Your CDMA has it's own identity, so does the SIM card you are putting in there. They are not the same. The SIM card supplied with the Sprint's TP2 is for roaming internationally, not inside the States.
