I had the VZW 8830 WE, verizon unlocked the device before i sold it so i could possibly make more money on it. The Tech told me something was built in internally to not allow Domestic / State-wide GSM to be used when a VZW Signal was detected. Dont know if that was just fluff, but i never left the country to see if it worked.
The New VZW BB's have a SIM slot to put any SIM after you unlock it, to be used on any Network...
