Sprint and verizon

[UpsidedownB]

So i am currently on the Verizon network and have a long time until my contract is up, I want the touch pro when released but if indeed is crippled by Verizon i want the sprint version. I have read in a few post but never got a full answer if i buy the sprint version is there any way to get Verizon to activate it. I saw one post saying that they thought that if the esn was low enough Verizon would do so but they charge ? I don't care about paying for it as long as i dont get a gimped phone.
