Helioseismic inferences of the internal rotation of the Sun are based on numerical inversions of rotational frequency splittings. The inversion matrix is positive and hence, it is possible to implement iterative inversion methodologies. In this work, we present an iterative inversion methodology based on an unstructured grid in both radius and latitude. The rotational splittings were calculated from 2304-day-long MDI time series, being the longest time series ever used to infer the solar internal rotation.
