I recently purchased an Iphone 4 that had been flashed to ntelos. I took the phone to verizon and it has a clean ESN, but they can't/won't flash it back to verizon.

I have tried restoring the phone with Itunes, doing a full reset/erase, and tried calling the Verizon OTA #. None of these things have worked? How can I get the carrier back to verizon? Thanks.
