flash iphone to page plus on ios 7?

i have a sprint iphone 4 on ios 7, i wanted to know if anyone knew of a way to flash it on to verizon/pageplus in its current state. oddly enough, it has a verizon meid which makes me think it has been flashed to verizon by a previous owner?

well anyway, the method cant include a jailbreak obviously. i have cdma workshop and qpst, so maybe a method using those apps?

thanks guys
