No, he wants the "housing itself" not something to go over it.
As in taking the insides of the Sprint Touch, out of its black casing (aka: the house) into an epmty green or white Touch (house/casing) and putting the "guts" of the Sprint Touch, inside of it.
He's looking for a CDMA version on this housing, because the GSM Touch is smaller.
GSM example shown here.
