I present two disparate examples of isospin violation in hadronic B-decays. In the first, the presence of ρ0-ωmixing in the decay B^∓→ρ^∓ρ0(ω)→ρ^∓π+ π- permits the extraction of sgn(sin α), where αis the usual angle of the unitarity triangle, with minimal hadronic uncertainty. In the second, the presence of π0-η,η' mixing can obscure the extraction of sin 2αfrom an isospin analysis in B→ππdecays.
