The goal of the SIMBA collaboration is to provide a global fit to the available data in inclusive B -> X_s gamma and B -> X_u l nu decays. By performing a global fit one is able to simultaneously determine the relevant normalizations, i.e. the total B -> X_s gamma rate and the CKM-matrix element |Vub|, together with the required input parameters, most importantly the b-quark mass and the b-quark distribution function in the B-meson, called the shape function. This strategy is analogous to the determination of |Vcb| from global fits to inclusive B -> X_c l nu decays. In this talk, we present preliminary results for the shape function and |C_7^incl Vtb Vts^*|, which parametrizes the total B -> X_s gamma rate, from a global fit to the available B -> X_s gamma measurements from BABAR and Belle.
