  We update our earlier study in [1], which was inspired by the 2002 SNO data,
on the implications of the results of the solar neutrino experiments for the
predictions of the effective Majorana mass in neutrinoless double beta-decay,
|<m>|. We obtain predictions for |<m>| using the values of the neutrino
oscillation parameters, obtained in the analyzes of the presently available
solar neutrino data, including the just published data from the salt phase of
the SNO experiment, the atmospheric neutrino and CHOOZ data and the first data
from the KamLAND experiment. The main conclusion reached in ref. [1] of the
existence of significant lower bounds on |<m>| in the cases of neutrino mass
spectrum of inverted hierarchical (IH) and quasi-degenerate (QD) type is
strongly reinforced by fact that combined solar neutrino data i) exclude the
possibility of cos(2 \theta_\odot)=0 at more than 5 s.d., ii) determine as a
best fit value cos(2 \theta_\odot)=0.40, and ii) imply at 95% C.L. that cos(2
\theta_\odot) \geq 0.22, \theta_\odot being the solar neutrino mixing angle.
For the IH and QD spectra we get using, e.g., the 90% C.L. allowed ranges of
values of the oscillation parameters, |<m>| \geq 0.010 eV and |<m>| \geq 0.043
eV, respectively. We also comment on the possibility to get information on the
neutrino mass spectrum and on the CP-violation in the lepton sector due to
Majorana CP-violating phases.
