We report measurements of the differential q2 spectrum and the forward-backward asymmetry for B → K(*) ℓ+ℓ-, where ℓ represents an electron or a muon, with a data sample of 253 fb-1 accumulated on the Υ(4S) resonance with the Belle detector at KEKB. We also present measurements of the branching fractions and their ratios.
