When you flash a rom like CM7 to a phone does that mean it can use any carrier? or the ones that are available. T-Mobile to Verizon, Verizon to cricket. etc.
And phones cannot be used for just any carrier. A sim unlocked Inspire can only be used on GSM carriers like ATT, T-mobile and their prepaid counterparts like Straight Talk. Verizon is a CDMA carrier and no matter what you do to the Inspire, it will never work with a CDMA carrier as such.
