BB 9650 verizon phone, programmed to t-mobile?

I just purchased a BB 9650 Bold on ebay. Verizon Bold, but it has been changed to t-mobile. I need to change it back to Verizon. Is there any way to change the phone back to verizon? I took it to verizon to activate and they couldn't because it was re-programmed for t-mobile. Any help would be very much appreciated.

huh? The only "programming" involved is going to Mobile Network, and changing the "Network Technology" from "GSM/UMTS" to "1XEV/CDMA".

I hope the Verizon employees aren't THAT dense
