Does the unlocked iPhone 5 work on CDMA network also?

If i buy a iPhone 5 unlocked from Apple, can i use the phone on Sprint or Verizon, with the iPhone IMEI number.

Not at present time, as even though the iPhone 5 sold via Apple is "unlocked" CDMA carriers still require program locked phones, even if they sell the same model. Neither Sprint or Verizon will accept outside phones at present time, taking advantage of the current DMCA laws that they paid for.
