  Charmless B->PP decays are studied using flavor SU(3) symmetry. Amplitude
with charming penguin topology is considered for two cases: with zero and with
arbitrary strong phase. Two sets of data (an older and the most recent one) are
used in the fits, so that the stability of the fits is tested. It is shown that
within the present uncertainties in the data the parameters of the fit may be
significantly modified, especially the gamma angle. The fits indicate the
strong phase of the charming penguin amplitude to be around $\pm 20^{o}$.
