We study the direct CP asymmetry in B--&gt;X(s)gamma decay in supersymmetric models with nonuniversal A terms. We show that the flavor-dependent phases of the A terms, unlike the flavor-independent ones, can give rise to a large contribution to the CP asymmetry while respecting the experimental bounds on the branching ratio of B--&gt;X(s)gamma decay and the electric dipole moments of the electron and neutron. The CP asymmetry of this decay is predicted to be much larger than the standard model prediction in a wide region of the parameter space. In particular, it can be of order 10%-15% which can be accessible at B factories.
