How do you flash a sprint phone over to boost mobile?

I like boost mobile's plans, just not their phones. How do I flash over a sprint phone to work on the boost mobile network ?

As Boost Mobile is wholly owned by Sprint Nextel they run on both Sprint's CDMA network and Nextel's iDEN network. Unlimited by Boost is designated for the CDMA handsets, while PayGo is for the iDEN side. http://answers.yahoo.com/question/accuse_write?qid=20090116162258AAe40mt&kid=FsMpCDe9BTFfsGioORosJ71M6dYT94QweaIQigryxylkYmKKjKt1&s=comm&date=2009-02-04+20%3A10%3A23&.crumb=

at this point sprint #s can't be ported over to boost mobile, and 'flashing' a cdma sprint phone to boost mobile isn't offered
