We discuss two models with 1 extra CP phase in transition. The CP phase with fourth generations, previously ignored, could impact on b→ sℓ+ℓ–, and , but does not affect EM and strong penguins. With SUSY at TeV scale, a right-handed “” squark can be driven light by flavor mixing. It does not affect b→ sℓ+ℓ–, but can generate while giving . B s mixing and would likely be large, and in B 0→ K *0 γ is promising.
