  We present a technique to determine the CP violating phases, as well as, the
lifetime differences of the mass eigenstates for both $B_d$ and $B_s$, by
considering correlated $B\bar{B}$ pairs produced at the $\Upsilon$ resonances.
We do not require a detailed time dependent study, but only partial time
integrated rates, with the tag time, either preceding or following the decay of
the other $B$ meson to a final state f. f may be a CP eigenstate or a non-CP
eigenstate.
