WebbFor injectivity, one could argue by dimension as in (i)$\Rightarrow$(ii), but here is a rephrasing of the same idea. It suffices to show that each $\theta_i:A/\m_A^ito R/\m_R^i$ is injective, since $\ker\theta$ must ``show up'' at some finite level if it is nonzero (Krull intersection theorem).
