We inspect consequences of the latest Bs mixing phase measurements on lepton flavor violation in a supersymmetric SU(5) theory. The O (1) phase, preferring a non-vanishing squark mixing, generically implies τ → (e + μ) γ and μ → e γ. Depending on the gaugino and the scalar mass parameters as well as tan β, the rates turn out to be detectable or even already excessive, if the RR mass insertion of down-type squarks is nonzero. We find that it becomes easy to reconcile Bs mixing phase with lepton flavor violation given: gaugino to scalar squared mass ratio around 1/12, both LL and RR insertions with decent sizes, and low tan β.
