In models of three or more scalar doublets, new CP violating phases appear in charged scalar exchange. These phases affect CP asymmetries in neutral B decays, even if Natural Flavor Conservation holds. The recent upper bound on the decay b → sγ constrains the effect to be at most on the order of a few percent. Modification of constraints on the CKM parameters open an interesting new region in the sin 2α-sin2β plane even in the absence of new phases.
