Help getting Verizon cdma TP2 over to Boost/sprint

[FilthyFletch]

Hi everyone this is my first post here. I know there has to be someone around who can help. Iu have a a verizon branded htc TP2 that i want to use on boost which is sprints cdma service. Im not sure what I really need to do whether its a custom rom or a flash or what not but figure it can be done some how as I see htc TP2 none subsidized no carrier brnaded phones on both verizon and sprint so must be a common way to debrand and make this verizon one work with sprint. the phone is off contract with verizon over a year. I have an evo 4 G on boost but want this as a secondary phone on the boost so I can dump my back up blackberry 8350 i for the TP@. Any help would be appreciated...Thanks in advance.
