Yeah...In fact, that's the only thread I found on the subject. What that thread is talking about is something different than I want to do.

The OP wants to be running two NAM's at the same time by running the phone software in a virtual machine. Way more complicated than anything I want to do. I just want to be able to switch between carriers. BTW, nothing I'm doing is illegal. I'm not duplicating the ESN and I'm maintaining my contract with Verizon. I simply want to use the same hardware with different providers without having the phone reprogrammed every time I travel.

You GSM people have it easy with your SIM card swapping...
