I just bought a used Droid X for my son. It may not seem like much, but he came from an Ally, so it's a big step up. At the time of purchase I verified with Verizon that the MEID was clean, and had no trouble activating the phone on Page Plus. What (if anything) can I do to disassociate the phone from the previous owner's account so that future actions of the previous owner don't affect the usability of this phone?
