  We analyze new sources of flavor violation in models with extra dimensions.
We focus on three major classes of five dimensional models: models with
universal extra dimension, models with split fermions, and models with warped
extra dimension.We study the implications of these new sources on the associate
CP violating asymmetries to the rare B-decays. We show that among these models
only the split fermions scenario may accommodate the recent experimental
deviation between the CP asymmetry of B_d -> phi K_S and sin 2 beta.
