I have a htc incredible and a droid x theyre orignally from verizon but I would like to get them flashed to cricket, but I was told that the esn of both cells is still active, would I be able to use flash them and use them one cricket even if the esn is active on verizon? I bought them from a guy on craiglist I tried to reach him to ask him to release the esn but he never replied.
