We report results on the Dalitz analysis of three-body charmless B+=>K+pi+pi-, B0=>K0pi+pi- and B+=>K+K+K- decays including searches for direct CP violation in the B+=>K+pi+pi- mode. Branching fractions for a number of quasi-two-body intermediate states are reported. We also observe evidence with 3.9 sigma significance for a large direct CP violation in B+-=>rho(770)0K+- channel. This is the first evidence for CP violation in a charged meson decay. The results are obtained using a Dalitz analysis technique with a large data sample of BBbar pairs collected with the Belle detector operating at the KEKB asymmetric energy e+e- collider. ; Comment: 6 pages, 3 figures, contributed to the Proceedings of HADRON'05, Rio de Janeiro, Brazil
