We present an up-to-date global analysis of solar, atmospheric, reactor and accelerator neutrino data in the frame work of three-neutrino oscillations. We discuss in detail the statistical significance of the observed hint of non-zero theta(13) in the solar sector at the light of the latest experimental advances, such as the Borexino spectral data, the lower value of Gallium rate recently measured in SAGE, and the low energy threshold analysis of the combined SNO phase I and phase II. We also study the robustness of the results under changes of the inputs such as the choice of solar model fluxes and a possible modification of the Gallium capture cross-section as proposed by SAGE. In the atmospheric sector we focus on the latest results for nu(e) appearance from MINOS and on the recent Super-Kamiokande results from the combined phases I, II and III, and we discuss their impact on the determination of theta(13). Finally, we combine all the data into a global analysis and determine the presently allowed ranges of masses and mixing.
