  We measure the branching fraction of the radiative B- decay B(B- -> phi K-
gamma) = (3.46 +/- 0.57^{+0.39}_{-0.37}) 10^-6, and set an upper limit on the
radiative B0 decay B(B0 -> phi K0 gamma) < 2.71 10^-6 at 90% confidence level.
We also measure the direct CP asymmetry of the B- -> phi K- gamma mode A_CP =
(-26.4 +/- 14.3 +/- 4.8)%. The uncertainties are statistical and systematic,
respectively. These measurements are based on 207 1/fb of data collected at the
Y4S resonance with the BABAR detector.
