We present measurements of decay amplitudes and triple-product correlations in B{yields}{phi}K* decays based on 253 fb{sup -1} of data recorded at the {upsilon}(4S) resonance with the Belle detector at the KEKB e{sup +}e{sup -} storage ring. The decay amplitudes for the three different helicity states are determined from the angular distributions of final-state particles. The longitudinal polarization amplitudes are found to be 0.45{+-}0.05{+-}0.02 for B{sup 0}{yields}{phi}K*{sup 0} and 0.52{+-}0.08{+-}0.03 for B{sup +}{yields}{phi}K*{sup +} decays. CP- and T-odd CP-violating triple-product asymmetries are measured to be consistent with zero.
