We study the upper critical field of the A and B phases in the triplet superconductor PrOs4Sb12 within the p+h-wave superconductivity proposed recently for this material. The present result is compared with Hc2(t) and H*(t), the boundary between the A and B phase in PrOs4Sb12, reported earlier and with more recent data of Hc2(t) for the single phase crystal. We find Hc2(t)'s for both the two phase crystal and the single phase crystal are described by the model for the A phase. From this fitting one can deduce the Fermi velocity as v=2.5 x 106 cm/s. On the other hand Hc2(t) for the B phase is found to be somewhat smaller than H*(t), which is rather puzzling.
