We report the first evidence for isospin violation in B ! K? and the first measurement of difference of CP asymmetries between B+ ! K+? and B0 ! K0?. This analysis is based on the data sample containing 772 ×106B ¯B pairs that was collected with the Belle detector at the KEKB energy-asymmetric e+e- collider.
