FYI - the first official Android 4.0 update from Samsung, labeled as XXLPQ (latest official version).

Well, there are some features missing from the earlier leaks, firmware XXLPH and XXLPJ, like there is no 3d anim effect in drawer and while swiping home screens, which was present in XXLPH and XXLPJ, but other than that, XXLPQ is cool. But i prefer XXLPH.
